Detection of surface antigen expression of pre- and post-cultured normal adult's bone marrow cells by using ABC
Abstract:
The expression of surface antigens on both normal adult's bone marrow and multipotential progenitor cells (CFU-Mix) was detected by use of ABC technique. The culture system of CFU-Mix was an ideal model for studying the differentiation direction of hematopoietic cells. The monoclonal antibodies (McAb) CD3, CD4, CD8 specific for T-lymphocytic lineage, CD22 for B-lymphocytic lineage and CD11, CD13, CD14 for granulocytomonocytic lineage were all demonstrated in certain proportion in cultured CFU-Mix, which might be associated with the control of hematopoiesis. A decrease in the positive rate of OKT9 and CD34 in cultured cells might be related to the differentiation of hematopoietic cells. SZ-2 and SZ-21 could contribute to the identification of the presence of megakaryocytes in CFU-Mix.
