We show that exposure of ME-SFCs from control subjects to TNF replicates the phenotypes we observed in ME-SFCs from endometriosis patients, including reduced decidualization (Figure 3A), reduced expression of ALDH1A1 (Figure 3B), increased expression of PDPN (Figure 3C), and enhanced migration capacity (Figure 4B). Here, ALDH1A1 is linked to endometriosis.
