针对 KG-1a 细胞制备的单克隆抗体 12-8 可识别大约 115 kd 的细胞表面抗原,并与 3% 至 4% 的骨髓细胞(包括大多数母细胞)发生反应。该抗原不表达于外周血细胞上。通过荧光激活细胞分选收集的表达 12-8 的骨髓细胞包含几乎所有单能(CFU-GM、BFU-E)和多能(CFU-MIX)集落形成细胞。分离的 12-8 个阳性骨髓群也含有这些集落形成细胞的前体。在采用经辐射的同种异体骨髓贴壁细胞的两阶段长期骨髓培养系统中,12-8个阳性细胞在十周内产生单能和多能集落形成细胞。此外,集落形成细胞的输出大大超过了输入。抗体 12-8 似乎可用于分析和可能富集造血祖细胞(包括集落形成细胞前体)。
A monoclonal antibody, 12–8, prepared against KG-1a cells, recognizes an approximately 115-kd cell surface antigen and reacts with 3% to 4% of bone marrow cells, including most of the blast cells. The antigen is not expressed on peripheral blood cells. Marrow cells expressing 12–8 collected by fluorescence-activated cell sorting contained nearly all of the unipotent (CFU-GM, BFU-E) and multipotent (CFU-MIX) colony- forming cells. The isolated 12–8 positive marrow population also contained precursors of these colony-forming cells. In a two-stage long- term marrow culture system employing irradiated allogeneic marrow adherent cells, 12–8 positive cells produced both unipotent and multipotent colony-forming cells for ten weeks. Moreover, the output of colony forming cells substantially exceeded the input. Antibody 12–8 appears useful for analysis and possibly enrichment of hematopoietic progenitor cells that include colony-forming cell precursors.
