多能造血干细胞(CFU-S)是造血组织中一组未分化的细胞群,它可根据需要而产生不同的血细胞。这些未分化的增殖细胞通常对电离辐射非常敏感,并且这些细胞的枯竭可造成机体的严重辐射损伤。因此很多学者反复研究了造血干细胞在恢复射线损害造血组织方面的作用。近来一些学者广泛注意到CFU-C的自身更新能力,认为受照射动物的CFU-C是由造血组织中原有活存的但非同一细胞群的CFU-S或CFU-C再生的,活存的CFU-S的子代对X射线
Multipotent hematopoietic stem cells (CFU-S) are a group of undifferentiated cell populations in hematopoietic tissue that produce different blood cells as needed. These undifferentiated proliferating cells are often very sensitive to ionizing radiation, and the depletion of these cells can cause severe radiation damage to the body. Therefore, many scholars have repeatedly studied the role of hematopoietic stem cells in the restoration of radiation damage to hematopoietic tissue. Recently, some scholars have widely noticed CFU-C’s self-renewal ability. It is considered that CFU-C of irradiated animals is regenerated from CFU-S or CFU-C originally existing in the hematopoietic tissue but not from the same cell group, Progeny of CFU-S to X-rays
