Cord blood derived CD34+ cells were co-cultured on irradiated stromal feeder layers, i.e. either on BM-MSCs or hES-MP002.5 cells. After 6 weeks, cells were harvested and analyzed for colony formation in standard methylcellulose. Numbers of CFU-E and CFU-GM generated per one thousand seeded CD34+ cells are shown as mean ± standard deviation from three independent experiments (n = 3). * p<0.05.
