A bit late but a paper from our lab has been published! Human fingertip regeneration is a fact, it happens in children and adults (not only in children as it has been long believed). We describe here the regenerative phases and analyse the proteome of wound exudates. www.nature.com/articles/s41...

It has been known for a long time that if the starting point of limb regeneration is at the hand level or close to the shoulder, it would take about the same time to regenerate. Puzzling right? Check out this preprint from our lab to know more about it: www.biorxiv.org/content/10.1...

Embryonic induction of fate is a core concept in developmental biology. But, cells can also modify the physical state of surrounding tissues a process we call 'actuation'. I reviewed with @mayorlab.bsky.social 3 excellent papers that show how actuation and feedback can drive changes in the embryo.

The Society for Developmental Biology has released a statement on how the Abrupt Dismissal of NIH and NSF Staff Undermines Government Efficiency. bit.ly/3X9VEKd

The Society for Developmental Biology (SDB) is alarmed by the recent workforce reductions at the National Institutes of Health (NIH), the National Science Foundation (NSF), and other federal research agencies. These sudden and far-reaching cutbacks jeopardize the breadth and depth of scientific inquiry—including in the field of developmental biology—and imperil immediate research goals, as well as long-term innovation, and the training of the next generation of scientists.

These dismissals do not enhance government efficiency. To the contrary, they eliminate highly trained experts, grant administrators, and support staff whose collective knowledge underpins critical discovery and fuels scientific momentum. Without their efforts, essential research— including research on birth defects, which kill twice as many children as cancer—will face considerable delays. The loss of such institutional memory will also undermine the capacity of these agencies to evaluate grants, maintain databases, and spearhead cutting-edge projects.

The SDB acknowledges the value of periodically reviewing and updating agency operations; however, large-scale workforce reductions taken without transparent input from those knowledgeable about these essential and complex agencies risks weakening the entire United States research enterprise. The consequences extend far beyond the laboratory bench, reducing our global competitiveness and hindering the development of breakthrough interventions for human health. Moreover, these actions, and the downstream effects on research teams, are causing trainees to rethink scientific research as a career. In short, these actions will erode the country’s leadership in the sciences, stifle innovation, limit job growth, and compromise the well-being of everyone in our society.

To mark the 40th year since the homeobox discovery, we've commissioned a series of articles from leaders in the field demonstrating the impact of the discovery on different disciplines. Check out the full collection: journals.biologists.com/dev/collect…

40 years of the homeobox
A large family of developmental genes share a 180 bp DNA sequence, called the homeobox, which encodes a DNA-binding domain. This year, 2024, marks the 40th year since the discovery of the homeobox in 1984, a landmark that fundamentally impacted several fields including genetics, developmental biology, neuroscience and evolution.

To celebrate this anniversary, Development has commissioned a series of articles from leaders in the field demonstrating the impact of the homeobox discovery on different disciplines. These review-type articles will be published throughout 2024, starting with an introductory Editorial and collated here. We hope you find these articles interesting and we welcome your future submissions detailing how this remarkable family functions in development, stem cells and regeneration.
