1. General information
DMM requires authors to submit their manuscripts online using the Bench>Press manuscript processing system. Authors are required to read our journal policies before preparing their manuscripts and all manuscripts should adhere to the journal’s terms of submission.
All presubmission or general editorial queries should be directed to the Editorial Office.
1.1. New submissions – format free
To make manuscript submission as easy as possible for authors, DMM offers format-free submission.
At first submission, authors may submit their manuscript in any format; however, for the benefit of Reviewers and Editors, we encourage authors to read the manuscript preparation guidelines below and to consider how easy a manuscript is to read (e.g. using appropriate line spacing, line and page numbers, and ensuring that figures are carefully numbered and/or accompanied by their legend).
All manuscripts must adhere to our guidelines regarding manuscript length.
1.2. Revised submissions
At DMM, roughly 85% of revised submissions are accepted for publication.
Authors should complete and submit a submission checklist with their manuscripts. This form asks authors to confirm that they have followed best practice guidelines regarding experimental subjects, data reporting and statistics. The checklist is based on the NIH Principles and Guidelines for Reporting Preclinical Research and is intended to help ensure high standards for reporting and to aid reproducibility.
2. Manuscript length
Research and Resource articles: the total length of the article should not exceed 8000 words, including the main text and figure legends, but not the title page, abstract, Materials and Methods section, or reference list (reference citations in the text do count towards the word limit). The total number of display items (figures, tables and boxes) must not exceed eight (8).
Note that final word limits will depend on the paper submitted and are at the discretion of the Editors.
3. Preparing the text and tables
The information below relates to a standard Research or Resource article. For all other article types, please refer to the guidelines provided on our article types page.
3.1 File formats
For manuscript text and tables, our preferred file format is Microsoft Word .docx (or .doc). We also accept Pages (.rtf format) and LaTeX.
Please include tables as part of the manuscript file. Tables must be editable and not embedded as an image.
Authors working in LaTeX can download and use our template. (Please note that the documents and guidelines apply to all of the Company of Biologists journals, including DMM.) Please upload a single PDF at first submission and include any component files, such as .st (style file), .cls (class file) and .bib (bibliography file), at submission of the revised version. Please note that LaTeX files will be converted to Microsoft Word files during the production process, and that authors will be required to check the conversion of symbols and special characters carefully at the proofing stage.
For mathematical equations, our preferred file format is MathType. We also accept Equation Editor (Microsoft Word) and LaTeX.
3.2. Article sections
3.2.1. Title page
This section should include a title of 120 characters or less (including spaces) that clearly and concisely summarises your specific findings (colons and specialist abbreviations should not be used), the full names (including middle initials) and affiliations of all authors (including present addresses for authors who have moved), and the corresponding author’s email address and ORCID identifier. Please note any cases where authors contributed equally to the work. Please also include 3-6 key words for indexing purposes (select key words that will make your manuscript easily searchable).
Click here for examples of well-written titles.
3.2.2. Summary statement
Summary statements are featured alongside your article details in the Table of Contents, and are a great way to bring the reader to your paper. Please provide a brief Summary statement of up to 30 words. It should explain, without overstatement, why someone should read the article. Please do not simply repeat the title, and avoid unfamiliar terms and abbreviations, as the text should be comprehensible to a broad scientific audience. We reserve the right to edit the text.
Please provide a brief abstract of no more than 180 words. This should succinctly and clearly introduce the topic of the paper (placing the study in the wider context of human disease), summarise the main findings, and highlight the significance of the data and main conclusions in terms of increasing our understanding or treatment of human disease. The conceptual advance and/or translational impact should be clearly written in a way that is accessible to a wide audience. For Resource articles, the translational implications of new methods and resources should be made clear.
The abstract is used by abstracting services without modification and is often read more frequently than the full paper, and therefore needs to be comprehensible in its own right. Do not include subheadings or references, and avoid any non-standard abbreviations.
Further information about how to write optimal titles and abstracts can be found here.
This section should succinctly provide the background information that is required to set the results into their proper biological context. It should not contain subheadings.
This section should describe the results of the experiments performed and should be broken up by subheadings to organise the findings presented and walk the reader through the results. Reproducibility of results must be included – see our submission checklist for further information. Please ensure that the distinction between new results and published findings/established facts is clear.
This section should explain the significance of the results and should place them into the broader context of the current literature. The discussion may contain subheadings to highlight important areas that are expanded on in the text.
3.2.7. Materials and Methods
This section should include sufficient detail to understand and replicate the experiments performed, in conjunction with cited references. All articles must contain instructions about how any new tool, model or reagent described can be obtained or accessed. To facilitate detailed description of materials and methods (allowing the reader to fully understand and replicate the experimental protocols), this section does not count towards the word limit for article length. The materials and methods should be divided into sections, and should include subsections detailing reagents, animal models and statistical analysis. Please provide names for ALL equipment and reagent suppliers. Give Latin names for all experimental species. Reporting standards should follow those recommended in our journal policies and submission checklist.
This section should mention any individuals or groups that are not named as authors, but have contributed to the research presented (e.g. in terms of reagents, time, expertise) or writing of the manuscript. Please also include details of support from core facilities.
3.2.9. Competing interests
Include a statement to identify any potential influences that readers may need to know about when thinking about the implications of the presented research. For more specific information regarding the affiliations and associations that must be disclosed, please see our journal policies page. Authors without financial or competing interests should explicitly assert this and include the statement ‘No competing interests declared’.
Details of all funding sources must be provided. It is the responsibility of the corresponding author to provide the relevant funding information from ALL authors. Please provide the official funding agency name as listed on the Crossref Funder Registry, i.e. 'National Institutes of Health', not 'NIH', and all relevant grant numbers. If your Funder is not listed in the Registry, please provide the name in full.
Where individuals need to be specified for certain sources of funding, please add initials after the relevant agency or grant number. Please use the following format: 'This work was supported by the National Institutes of Health [AA123456 to C.S., BB765432 to M.H.]; and the Alcohol & Education Research Council [hfygr667789]'. Where no specific funding has been provided for the research, please state ‘This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors’.
All publicly available datasets supporting your work should be included in the data availability section. Details should include the repository name, identifier such as accession number or DOI and, where possible, include a hyperlink to the URL of the dataset. Datasets should be made publicly available at the time of publication. For more information on our data deposition requirements, please see our journal policies.
Please note that DMM endorses the Force 11 Data Citation Principles and recommends that references to datasets should also be included in the reference list with DOIs/accession numbers and hyperlinks, where available.
DMM uses the CRediT taxonomy to define author contributions to primary research papers and requires that the independent contributions of each author be provided during online submission. The information provided during submission will be used to generate an author contributions statement that will be included in the final published article and should be checked at proof stage. The journal policy page provides more information.
All references cited in the text, tables and figure legends should be included in a single reference list at the end of the article. We strongly encourage the citation of the primary literature over review articles wherever possible and for this reason do not have a limit on the number of references that can be included. For specific information about reference formatting, please see the references section below.
Figure legends should be listed at the end of the manuscript. The first sentence of the legend should summarise the figure and be in bold. Each figure legend should stand alone and should contain enough information to ensure that the figure is understandable without having to refer to the main text. Figure panels should be labelled with uppercase letters (A, B, C, etc.), and each panel should be described in the legend. Any abbreviations not given in the main text should be defined. For further details on what should be included in figure legends, please refer to our submission checklist.
3.3.1. General information
- Prepare manuscripts in English (either US or UK spelling is acceptable, but be consistent within the manuscript). Your writing should be comprehensible to Editors and Reviewers, and your writing style should be concise and accessible. If English is not your first language, please consider using a language editing service prior to submission.
- Ensure that the language in your manuscript is original and does not contain previously published passages of text (including those from your own publications) – see our journal policies for more details. All accepted manuscripts are routinely screened using plagiarism-detection software.
- Use double line spacing and continuous line numbering throughout the paper in order to facilitate online reviewing.
- Please ensure pages are numbered.
- Do not embed figures in the text.
- Cite each figure, table and movie in the text in numerical order. Figure or table parts should be labelled with uppercase letters (A, B, C, etc.). Use the following format for citations: Fig. 1A,B or Figs 1 and 2, or Table 1 or Movie 1.
- If necessary, display equations should be cited using the following format: Eqn 1.
- For supplementary figures, tables and equations, cite as Fig. S1, Table S1 or Eqn S1.
- Define abbreviations at first mention.
- For special characters not available on a standard keyboard (e.g. Greek characters, mathematical symbols), use the Symbol font or the ‘Insert Symbol’ function in Microsoft Word, where possible. For special characters that are not available via this route, please use MathType characters; do not use embedded images (e.g. GIF).
3.3.2. Units and nomenclature
- Units of measurement should follow the SI system, e.g. ml s-1 rather than ml/s. Guidance on using the SI convention can be found here. Type a space between a digit and a unit, e.g. 1 mm (except 1%, 1oC).
- Use s.e.m. and s.d. for standard errors, etc.
- Taxonomic nomenclature: the Latin names and taxonomic authority (e.g. Linnaeus) should be provided for all experimental species. All species names should be italicised.
- Genetic nomenclature: gene names should be in italic type, but the protein product of a gene should be in Roman type. Genetic nomenclature should be in accordance with established conventions and should be approved by the relevant nomenclature curator if applicable. See below for some relevant links.

18.104.22.168. References in text
References in the text should be cited using the Harvard (name, date) referencing system.
Each reference cited in the text must be listed in the Reference list and vice versa: please check these carefully. Where references are cited only in the supplementary information, please provide a separate supplementary reference list and do not include these in the main reference list.
Literature citations in text are as follows.
- One author – (Jones, 1995) or (Jones, 1995; Smith, 1996).
- Two authors – (Jones and Kane, 1994) or (Jones and Kane, 1994; Smith, 1996).
- More than two authors – (Jones et al., 1995) or (Jones et al., 1995a,b; Smith et al., 1994, 1995).
- Manuscripts accepted for publication but not yet published: include in reference list and cite as (Jones et al., in press).
- Manuscripts posted on preprint servers but not yet published: include in reference list and cite as (Smith et al., 2016 preprint).
- PhD theses: include in Reference list and cite as (Smith, 2016).
- Website URLs: cite in the text but do not include in the Reference list; provide the URL and, if the website is frequently updated, the date that the site was accessed.
- Citation of unpublished data: we strongly discourage the citation of unpublished data or data not shown. Where it is necessary, use the format (S.P. Jones, unpublished observations/data not shown); note that the Editor or journal editorial office might request that these data should be included prior to publication. Personal communications (the unpublished observations of scientists other than the authors) can only be cited when substantiated by written permission (e.g. by email) from the scientist in question and should be cited in the text using the format (full name, institution, personal communication). Unpublished work cannot be included in the Reference list.
- Datasets: we recommend that all publicly available datasets are fully referenced in the reference list with an accession number or unique identifier such as a DOI. Cite as (Jones and Jane, 1994).
- Authors should avoid citing articles from journals that are suspected to be predatory in nature (see https://thinkchecksubmit.org/ for an online resource designed to help researchers identify trusted journals).
- Citation of retracted articles is strongly discouraged. If it is necessary to cite a retracted paper, the notice of retraction must also be cited and it must be obvious to the reader that the article has been retracted. Editors may question why a retracted publication has been cited.

- If there are more than 10 authors, use 'et al.' after the 10th author.
- Within a group of papers with the same first author, list single author papers first, then papers with two authors, then papers with more than two authors. If more than one reference exists for each type, arrange by date order. Use a and b for papers published in the same year.
- 'In press' citations must have been accepted for publication and the name of the journal or publisher included.
3.4. Preparing tables
Prepare tables in ‘cell’ format and include in the same file as the main text. Tables must be editable and not embedded as an image.
The title of the table should be a single sentence and should summarise the contents of the table. Details referring to one or more isolated item(s) in the table are best given in a table footnote. Units should be given in parentheses at the top of each column (do not repeat in the table).
3.5. Preparing display equations
Our preferred file format for equations is MathType. We also accept Equation Editor (Microsoft Word) or LaTeX.
Please number all display equations consecutively. They should take the form:
Units should be defined in the text rather than included in the equation.
4. Preparing figures
Figures should be numbered in a single series that reflects the order in which they are referred to in the text.
Figures should be prepared at the smallest size that will convey the essential scientific information; final figure size is at the discretion of the journal. For further information on how to arrange your figures to optimise viewing by reviewers and readers, see our figure layout guidelines.
At initial submission, you may submit a single PDF file containing all text and figures (ensure figures are numbered and accompanied by their legend). Once an article has been accepted for publication, you are required to submit separate files for each figure (see below for file formats).
Figure legends should be included in the main text file and not in the figure file.
There are no charges for the use of colour in figures, although gratuitous use of colour in graphs and diagrams should be avoided and colour should only be used to improve scientific clarity.
We strongly encourage the use of colours that are suitable for colour-blind readers, particularly in the preparation of fluorescence microscopy images. Most notably, we discourage the use of red/green for the display of 2-channel images; authors should consider an alternative colour combination (e.g. magenta/green).
4.2. Preparing photographic images
4.2.1. General information
Photographic images (also known as bitmap images) are made up of pixels (e.g. light, fluorescence and electron microscopy, gels, and traditional photography)
- The maximum figure size, including lettering and labels, is 180 mm x 210 mm.
- Images should be saved at a resolution of 300 pixels per inch. Any image quality option should be set to maximum.
- For figures that contain both photographs and line art or text, 600 pixels per inch is preferred.
- For micrographs, use a scale bar to show the magnification and give the length of the scale bar in the figure legend.
- Colour: supply images in RGB (not CMYK) mode, as this maximises colour quality and is how the figures will be displayed online; do NOT use Spot, Pantone or Hex colours and do NOT assign a colour profile.
- Text labelling: use 12 pt bold uppercase letters (A, B, C, etc.) to distinguish figure panels. Other labelling should be 8 pt Arial font (sentence case) and headings should be bold. For gene sequences, use Courier font to ensure that each letter is the same width. Use Symbol font for Greek characters.
4.2.2. File formats
Accepted file formats are: EPS, PDF, TIFF, JPEG.
- Arial or Helvetica must be the font choice used throughout figure preparation.
PowerPoint images: we do NOT accept PowerPoint files. Instead, please save as PDF using the instructions below.
- Go to ‘print’ and then choose 'Save as PDF' in the print dialogue box
- You can download free software that will enable you to print EPS, PDF files to disk:
4.3. Preparing graphs and diagrams (line art)
4.3.1. General information
- The maximum figure size, including lettering and labels, is 180 mm × 210 mm.
- Line thicknesses and symbols should be of sufficient size to ensure clarity if the figure is reduced in size.
- For graphs, our preferred symbols are filled and open circles, triangles, squares, or diamonds; where possible, the same symbol should be used for the same entity in different figures.
- Colour: supply line art in RGB (not CMYK) mode, as this maximises colour quality and is how the figures will be displayed online; do NOT use Spot, Pantone or Hex colours and do NOT assign a colour profile.
- Text labelling: use 12 pt bold uppercase letters (A, B, C, etc.) to distinguish figure panels. Other labelling should be 8 pt Arial font (sentence case) and headings should be bold. For gene sequences, use Courier font to ensure that each letter is the same width. Use Symbol font for Greek characters.
4.3.2. File formats
Authors should submit their source figures in an editable format (vector graphic) that retains font, line and shape information. This format ensures that we can edit where necessary and produce high-quality online PDFs.
We accept the following file formats for graphs/line art: EPS, PDF and WMF.
- Applications such as Adobe Illustrator, Canvas, DeltaGraph, Corel Draw, Freehand, MatLab and SigmaPlot provide these formats.
- Please ensure that you 'export' or 'save' with (text/font) information included
- Save text/font information as ‘text’, not ‘curves’ or ‘outlines’.
- If combining images, always 'embed' images; do NOT simply 'link' them. In Adobe Illustrator, copying and pasting or dragging an image directly from Adobe Photoshop will embed the image. Alternatively, if you use the 'Place' command, uncheck 'Link' in the dialogue box. For other software applications, please refer to the documentation (often there will be a 'link', 'proxy', 'OLE' or 'OPI' option, which must NOT be used with EPS files).
- Note that submission of JPEG or TIFF format for graphs/line art may delay production of your article.
4.4. Image manipulation
Any alterations made to figures using computer software must be consistent with our image manipulation policy. The images presented in the manuscript must remain representative of the original data; the corresponding author will be asked to confirm this at submission. Please read our requirements for preparing your figures to avoid a potential delay in the publication process or rejection on the basis of non-compliance with these guidelines. This guide also includes recommendations for improving figure layout to help reviewers and readers appreciate your data.
All accepted manuscripts are routinely screened by our production department for any indication of image manipulation. If evidence of inappropriate manipulation is detected, the journal might ask for the original data to be supplied and, if necessary, may revoke acceptance of the article.
4.5. Figure permissions
It is the responsibility of the author to obtain permission to use figures from another publication in any article submitted to DMM and to ensure that any such use is credited to the source. If you are reproducing material from a non-Open Access licence source, please state so as follows: 'This image is not published under the terms of the CC-BY licence of this article. For permission to reuse, please see (Author et al., 2016)'. Any fees associated with use of the figure are the responsibility of the author. Written permission from the author and/or publisher of the original material, as appropriate, should be provided at the time of submission, otherwise publication may be delayed. If a figure has been modified from a previously published figure, please check with the copyright owners to see whether permission is required and include a complete citation/reference for the original article.
5. Preparing movies
Our preferred file format for movies is .mp4, but we also accept .mov. Movies should be prepared at the smallest file size that will convey the essential scientific information. We have a limit of 500 MB for all movie files. If your movies exceed this limit, please contact the Editorial Office for advice before submission.
Please include the titles and captions of all movies in your supplementary information PDF (see section on preparing supplementary information). Please keep captions as short as possible and ensure that they explain what is being shown in the movie and any necessary details of how the movie was made.
Movies should be numbered in a single series that reflects the order in which they are cited in the text, e.g. see Movie 1. Movie 2, etc. Please do not use alphabetical labelling, e.g. Movies 1A-C should be relabelled as Movies 1-3.
All movies will play in place in the full-text online version of the article and a link to each movie will be included in the supplementary information PDF.
When preparing your movies, please note the recommendations below:
- Use a resolution of no greater than 1280x720 (720p), as most readers will view on a desktop or mobile device
- Use a well-characterised video compression codec such as H.264 and use multi-pass encoding if available
- Do not exceed a bit rate of 2500mbps for 720p H.264-encoded video
- Keep the duration to the minimum required to illustrate your point
- Do not include an audio track unless it is essential
- If including audio, use a well-characterised audio compression codec such as AAC
- Do not exceed a bit rate of 128kbps, sample rate of 44.1kHz, or channel count of 2 for encoded audio
Please note that we reserve the right to make movies or other data forms available on an Open Access basis via The Company of Biologists’ website, YouTube and other online channels. Where we do, the movies and other data forms may on occasion be made available under the terms of the Creative Commons Attribution 4.0 International (CC-BY) Licence (the terms of which are set out at https://creativecommons.org/licenses/by/4.0/legalcode). These terms permit the copying and/or adaptation of the movie and the distribution of the movie or any such adaptation by any means and in any medium or format to any other person, including for commercial purposes, provided that you are credited as the original author. There would be no additional cost to you, the author.
6. Supplementary information
Data that are essential for interpretation of the results of the main paper should be included in the main paper. Supplementary information provides access to supporting data that do not appear in the full-text article or PDF, but that accompany the final version of the paper online.
These data are peer reviewed and subject to the same criteria as the data that are to be published in the paper itself. During peer review, Editors and reviewers are asked to assess whether the supplementary information is appropriate and essential for supporting the findings of a paper.
All supplementary information will be strictly limited to a total of 50 MB per article (excluding movie files and cover art submissions).
Supplementary material may include movies, figures and tables. Descriptions of computational/mathematical analyses and further details of experimental protocols already described in the Materials and Methods section of the main article may be included as supplementary Materials and Methods; the main article must, however, contain sufficient information to allow the reader to understand all experiments performed. Tables comprising datasets or listing materials such as oligonucleotide primers, antibodies or strains may be provided as supplementary material. We do not accept additional Results or Discussion text as supplementary material. Very large files or those requiring specialist software are not suitable as supplementary information. For large datasets, e.g. imaging data, please see our guidelines on data deposition.
With the exception of movies (see section on preparing the movies) and large tables, all supplementary information, including movie titles and captions, should be collated into a single PDF file. If your table is very large, or you wish readers to be able to export and/or manipulate the data, we would prefer you to submit it as a Microsoft Excel file.
Use a separate numbering system from that used in the main article and use the format Fig. S1, Fig. S2, Table S1 etc. If a supplementary figure relates to a particular figure in the text, please cite it as close to this figure as possible. For the convenience of readers, please place each figure next to the corresponding legend in the supplementary information PDF. Please include a legend for each figure and a title for each table.
Please note that supplementary data files are not copyedited by DMM and therefore authors must ensure that all files are checked carefully before submission and that the style of terms and figures conforms to that of the article. Modification of supplementary information after publication will require a formal correction.
Refer to each piece of supplementary information at least once within the text of the main article.
