本文作者使用脐带血中分离的单个核细胞(CBMCs)研究了rIL-2对未分群及去除T 细胞、单核细胞的CBMCs 的增殖及IgM 合成的影响。结果表明,rIL-2在体外可以诱导未活化的CBMCs 产生显著的剂量依赖性增殖,甚至在去除T 细胞及单核细胞后,rlL-2仍能 The authors used cord blood mononuclear cells (CBMCs) to study the effects of rIL-2 on the proliferation and IgM synthesis of non-clustered and T-cell and monocyte-derived CBMCs. The results show that rIL-2 can induce significant dose-dependent proliferation of unactivated CBMCs in vitro, even after removal of T cells and monocytes
