The influence of different oxygen concentration on the ex-vivo culture of cord blood HSPCs (n = 4). a The total nucleated cells (TNCs) and CD34+Lin− cell numbers in 3% and 20% O2 groups on day 7. b The TNCs and CD34+Lin− cell number in 1% and 20% O2 groups. c The TNCs and CD34+Lin− cell number in coculture and suspended culture group (solo) at 1% O2. d The percentage of CD34+Lin− cells in the different groups. *P < 0.05, **P < 0.01
