Contraction of collagen disc by control and transforming growth factor β1 (TGF-β1)-treated stromal cells from the endometrium (EndoSCs), dermis (DermSCs), or adipose tissue (AdipoSCs). (A) Representative photographs of porcine collagen discs embedded with stromal cells in different quantities (40 * 10³, 80 * 10³, 160 * 10³) taken at 48 h of experiment in TGF-β1-treated and control groups. (B) Graphs reflecting basal contraction of discs embedded with EndoSC, DermSC, or AdipoSC and effect of TGF-β1. Disc size (%) was calculated as the area of disc/area of well. Data presented as mean ± SD; paired t-test was used for statistical analysis; *p < 0.05.
