摘要

C,57,BL/6小鼠经,60,Co γ射线一次整体照射8 Gy后，分成三组：（1）单纯照射8 Gy组，（2）照射后单纯骨髓移植组，（3）照射后混输脾基质细胞（SSC）与骨髓细胞（BMC）组，以观察骨髓移植和回输脾基质细胞对大剂量照射后受体存活率及造血干细胞（CFU-S）的影响，并初步探讨其可能的机理。结果表明：单纯骨髓移植组受体存活率比单纯照射组高出27%；而照射后混输SSC组之存活率比单照射组高47%，比单纯骨髓移植组高22%（P,<,0.05）。混输SSC可明显提高脾CFU-S、CFU-F及ANAE染色,（+）（-）,细胞数。在体外混合培养中脾基质细胞对实质细胞增殖起支持与调节作用。

Abstract

The paper reported that C,57, BL/6 mice after exposure to 8Gy γ-rays irradiation were divided into three groups: (1) the control group (8 Gy only),(2) the group with bone marrow cell (BMC) injection only,(3) the group with mixed injection of BMC and splenic stromal cell (SSC) which cultured in order to observe the effect of bone marrow transplantation and injection of SSC on the survival rate of recipients and on the number of hemopoietic stem cells (CFU-S) after large dose irradiation and study its mechanism. The results of experiments suggested that the survival rate of recipients of the group with BM cells injection only was 27% higher than that of the control group, but that of the group with SSC mixed injection was 49% higher than that of the control group and 22% higher than that of the group with BMC injection only. The CFU-S shows that mixed SSC injection improve the number of CFU-S,CFU-F and ANAE,[+][-], lymphocyte in spleen significantly. The cocultivation of spleenocytes and SSC in vitro showed the spleen stromal cells surport and regulate their parenchyma cells.
