BMP signaling-dependent dorsal-to-ventral gradient of PAX3/7 transcriptional activity revealed by the P34::tk::LacZ reporter. Left: expression patterns of neural progenitor (NP) and interneuron (IN) TF markers in the developing spinal cord. Right: Immunostaining for β-galactosidase (β-gal; red/grey), GFP (blue/grey) and either OLIG3 (green/grey) or pSMAD1/5/9 (green/grey) on transverse sections of E9.0 (bottom) and E9.5 (top) P34::tk::LacZ; Pax3+/GFP spinal cords at brachial level. Black and white panels show magnified views of the boxed region.

How do pleiotropic TFs generate organized diversity in developing tissues? @spinalorga.bsky.social shows that PAX3 & PAX7 organize #SpinalCord by acting as both repressors & pioneer activators, regulated by #morphogens to ensure precise neural subtype specification @plosbiology.org 🧪 plos.io/4qumsla

Schematic of how Vangl2 regulates cellular organization in both local and distant compartments through a vinculin-dependent mechanism. Left: Wildtype. Right: Localized Vangl2 deletion. The deletion of Vangl2 in either the greater epithelial ridge (GER) or the organ of Corti results in defects in cellular organization, such as the misorientation of hair cells and GER cells. These defects occur in the local and distant compartments, the latter via a vinculin-dependent process termed “compartment coupling”.

Researchers have used engineered cellular 'organisers' to instruct stem cells to form specific tissues and organs. The findings have huge potential for the future treatment of chronic diseases like diabetes and Parkinson's disease.
