Aberrant Mechanical tension-activated TGFβ1-SMAD2/3 signaling, synergized with Cdc42 deficiency, in AT2 alveolar cells causes peripheral-to-center progression in🐭post-lung lobe resection

Dr. Jingyu Chen & Nan Tang labs @cellpress 2019

Interesting, ablation of TGFβR2 in Cdc42 KO AT2 cells blunts fibrotic expansion w/o rescuing

In contrast, Normalizing the ectopic mechanical tension post-lung lobe resection, using a unique silicon prosthesis, rescues both alveolar regeneration & fibrosis
