Fibroblast growth factors stimulate proliferation of AdMSC and UCB stem cells. AdMSC and UCB stem cells were cultured in low serum media supplemented with 10 ng/ml FGF2 or FGF5 for 48 h. Cells were pulsed with BrdU for 2 h prior to fixation. FGF2 inhibited proliferation of UCB (a). FGF5 increased proliferation of UCB stem cells (b). * = p < 0.05
