We describe the preparation of novel fluorescent derivatives of rabbit muscle actin and bovine tubulin, and the use of these derivatives to study the behaviour of actin filaments and microtubules in living Drosophila embryos, in which the nuclei divide at intervals of 8 to 21 min. The fluorescently labelled proteins appear to function normally in vitro and in vivo, and they allow continuous observation of the cytoskeleton in living embryos without perturbing development. By coinjecting labelled actin and tubulin into the early syncytial embryo, the spatial relationships between the distinct filament networks that they form can be followed second by second. The dynamic rearrangements of actin filaments and microtubules observed confirms and extends results obtained from previous studies, in which fixation techniques and specific staining were used to visualize the cytoskeleton in the Drosophila embryo. However, no tested fixation method produces an exact representation of the in vivo microtubule distribution.
Development Journal Meeting 2022: From Stem Cells to Human Development
-JournalMeeting.png?versionId=3737)
Following a virtual meeting in 2020, we are delighted to announce that the fifth iteration of our popular Journal Meeting will be held from 11-14 September 2022 at the historic Wotton House, Surrey. Registration is open now.
Special Issue: The Immune System in Development and Regeneration
(update)-ImmuneSI.png?versionId=3737)
Our latest special issue is now complete. It showcases articles that add to the repertoire of immune cell functions during development, repair and regeneration, and provide insights into the developmental pathways leading to the generation and dispersal of these cells.
Propose a new Workshop
-GSWorkshop.png?versionId=3737)
Our Workshops bring together leading experts and early-career researchers from a range of scientific backgrounds. Applications are now open to propose Workshops for 2024, one of which will be held in a Global South country.
Preprints in Development
(update)-InPreprints.png?versionId=3737)
As part of our efforts to support the use of preprints and help curate the preprint literature, we are delighted to launch a new article type: ‘In preprints’. These pieces will discuss one or more recent preprints and place them in a broader context. You can read the first article here.
FocalPlane Network launched
-FocalPlaneNetworkLaunch.png?versionId=3737)
Like the Node Network, the aim of the FocalPlane Network is to facilitate promotion and networking as well as assist those seeking conference speakers, committee members, reviewers or collaborators. We hope that it will help promote diversity in the community. Find out more and join the Network here.
