Effect of hypoxia on endometrial MSC proliferation in serum-free media. Endometrial MSC cultured in DMEM/SF/FGF2/EGF on fibronectin in (A) normoxia (20% O₂) and (B) hypoxia (5% O₂). (C) Proliferation of endometrial MSC cultured in serum-containing, serum-free, and xeno-free media on various matrices in hypoxia (gray bars) or normoxia (black bars) as measured by MTS viability assay on day 7. Data are mean±SEM (n=3 samples from three different patients). Values for each condition for each patient sample were means of triplicate wells. *p<0.05.
