From: TGFβ1-transfected tendon stem cells promote tendon fibrosis
TGFβ1 overexpression in tendon stem cells increases the expression levels of chondrogenic and fibrogenic markers. A The mRNA level of TGFβ1 in TGFβ1-TSCs. B The mRNA levels of aggrecan and COL2A1 in TGFβ1-TSCs. C, D The protein levels of phosphorylated (p)-Smad2, collagen type II (Coll), aggrecan, and α-SMA in TGFβ1-TSCs. TSC: tendon stem cell; OE: overexpression. *p < 0.05, **p < 0.01, ***p < 0.001.
