Figure 3From: Effects of hypoxic culture conditions on umbilical cord-derived human mesenchymal stem cellsA. The effect of hypoxia on the cell growth of the UC-derived stem cells from all donors (n = 4). Data represent the mean ± SD (*p < 0.05) B. Western Blot of HIF-1α protein expression at different O2 concentrations following a 72 h incubation of the MSC populations. The expression of β-actin served as a loading control.Back to article page
