A developmental atlas of zebrafish gills links early vascular patterning to adult architecture
Summary: An atlas of zebrafish gill vasculature reveals developmental asymmetries and shows how early vascular patterning shapes filaments and lamellae and is reflected in adult gill architecture.

Cell-cell junction proteins like ZO-1 not only play a critical role in the mechanical interaction between cells, but also participate in the biochemical signalling to coordinate the cell sheet. Check out this review on collective cell migration here to learn more: doi.org/10.1016/j.cd...

Maybe it's time we rethink the idea that development is a cell centric process? In this beautiful review, María-del-Carmen and @stramerlab.bsky.social discussed how the ECM underlies and influences many morphogenesis processes from wing unfolding to mammary gland development.
