Myofibroblast activation
WebMar 20, 2006 · Myofibroblast activation is Galectin-3 dependent. ( a) Galectin-3 expression is up-regulated in myofibroblasts during the hepatic fibrotic response in vivo. Liver sections from WT control (olive oil) ( i – iii) and chronic CCL 4 injured (8 weeks) ( iv – vi) mice were stained with Galectin-3 antibody (green), anti-αSMA (red), and DAPI (blue). WebApr 9, 2024 · In addition, activation of ERK1/2 by Ang II is dependent on TGF-β . The findings from our study demonstrated that inhibition of either Smad3 or ERK1/2 activities attenuate TGF-β1-stimulated myofibroblast differentiation. Therefore, TGF-β1 mediated myofibroblast transdifferentiation of adult HCFs through the Smad and ERK1/2 cascades.
