Partial #EndMT,by #Hypoxia-induced CD45, as a major cellular source for neointima formation

50% ECs in ligated artery are CD45+

CD45 is required to maintain this Partial status
Amazing!

How CD45 titrates the extent of mesenchymalization of #EndothelialCell?

CD45 stabilizes VE-cad junction via fortifying integrin α11-SHARPIN complex

Very interesting data on Biomechanics of #EndMT

What (beyond CD45) control partial-to-complete EndMT transition?

Link b/wKLF2 & #EndMT?
EC secretome? So interesteing
