淋巴系祖细胞即T、B淋巴系集落生成单位(TL-CFUc与BL-CFUc)。它是由造血干细胞(HSC)分化而来的、且能进一步分化成熟为T、B淋巴细胞的一类过渡性细胞群体。 T、B细胞除在机体免疫系统中具有重要的细胞和体液免疫功能外,在血液学、组织器官移植、肿瘤和遗传学诸方面亦起着重要作用。因而,对淋巴细胞的研究,引起了各国学者的极大兴趣和关注,并进行了广泛的探索研究。特别是近一、二十年来,造血干细胞实验技术的建立和免疫学的发展,为进一步研究
Lymphoid progenitor cells, T, B lymphoid colony forming units (TL-CFUc and BL-CFUc). It is a group of transitional cells differentiated from hematopoietic stem cells (HSCs) and capable of further differentiating into T, B lymphocytes. T and B cells play an important role in hematology, tissue and organ transplantation, oncology and genetics in addition to important cellular and humoral immune functions in the body’s immune system. Therefore, the research on lymphocytes has aroused great interest of scholars in all countries and concerns, and conducted a wide range of exploration and research. Especially in the past one or two decades, the establishment of experimental techniques of hematopoietic stem cells and the development of immunology have provided theoretical basis for further research
