刺激型抗人血小板单克隆抗体──ＨＩＰ_２在体外有刺激人造血祖细胞集落形成的作用。本研究结果显示：ＨＩＰ_２对正常人和急性髓系白血病（ＡＭＬ）初诊及缓解患者的粒单系造血祖细胞（ＣＦＵ－ＧＭ）集落产率有明显刺激作用，而对ＡＭＬ祖细胞（ＣＦＵ－ＡＭＬ）集落产率无明显刺激作用，为临床ＡＭＬ患者在化疗抑制期及骨髓移植造血抑制期用该抗体加速造血恢复提供了实验依据。 The stimulatory anti-human platelet monoclonal antibody, HIP2, has the effect of stimulating colony formation of human hematopoietic progenitor cells in vitro. The results of this study show that HIP_2 significantly stimulates the colony yield of CFU-GM in the initial diagnosis and remission of normal and acute myeloid leukemia (AML) patients, whereas it affects AML progenitor cells (CFU-AML). ) The colony yield has no obvious stimulatory effect, which provides experimental basis for the clinical AML patients to accelerate the hematopoietic recovery with the antibody in the chemotherapy inhibition period and bone marrow transplantation hematopoietic suppression period.
