The distribution of the extracellular matrix molecules fibronectin, laminin and entactin was studied in frozen sections of 9½-day mouse embryos in order to relate their presence to neural crest cell migration. It was found that all three components were present in basement membranes, laminin and entactin being mainly restricted to these. Fibronectin was present at high levels in basement membranes and extracellular spaces throughout the embryo, including the regions of neural crest cell migration. Fibronectin is known to affect migration in a variety of cell systems, so its presence in the embryo at the time of migration may indicate that it is influencing cell movement. This influence is likely to be via the cell surface through interactions with other matrix components such as glycosaminoglycans, and possibly entactin and laminin.
Development Journal Meeting 2022: From Stem Cells to Human Development
-JournalMeeting.png?versionId=3773)
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=3773)
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. You can watch recordings from our Development presents... webinar celebrating the special issue here.
Propose a new Workshop
-GSWorkshop.png?versionId=3773)
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=3773)
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=3773)
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.
