Human erythrocytes O,Rh+ (D) coated with hyperimmune human anti-serum formed rosettes primarily with monocytes in peripheral blood mononuclear cell suspensions. The rosetting cells (EAhu-FRC), separated on a Lymphoprep gradient were found in the pellet and were up to 95% pure monocytes as judged by cytochemical criteria. A two step procedure involving depletion of T lymphocytes followed by the isolation of EAhu-RFC yielded monocytes up to 98% pure. The isolated cells did not respond to mitogens in vitro, but they act as accessory cells in mitogen-induced T lymphocyte proliferation. This simple method may be useful in studying monocyte function in human disease as it does not require a large amount of blood.
用人抗血清包被的人O型、Rh+(D)红细胞,主要在外周血单核细胞悬液中与单核细胞形成玫瑰花结。在淋巴细胞分离液梯度上分离得到的玫瑰花结形成细胞(EAhu-FRC)存在于沉淀中,根据细胞化学标准判断,其单核细胞纯度高达95%。采用两步法,先去除T淋巴细胞,再分离EAhu-RFC,可得到纯度高达98%的单核细胞。分离出的细胞在体外对有丝分裂原无反应,但在有丝分裂原诱导的T淋巴细胞增殖中起辅助细胞的作用。这种简单方法可能有助于研究人类疾病中的单核细胞功能,因为它不需要大量血液。
