The UCB samples were mixed with the Hetasep solution (StemCell Technologies, Vancouver, Canada) at a ratio of 51, and then incubated at room temperature to deplete erythrocyte counts. The supernatant was carefully collected and mononuclear cells were obtained using Ficoll density-gradient centrifugation at 2,500 rpm for 20 min. The cells were washed twice in PBS.: b, p! k1 z' g9 g* p4 j! I5 a
疑惑1.Hetasep solution是指的红细胞裂解液么 ?! z( g3 {+ ~1 P" w9 s3 e. U
