造血细胞的增殖及成熟是由很多因素控制的,其中应考虑到某些激素。激素的作用多数通过环3′,5′-AMP(cAMP)为媒介。其他作者已证实β-肾上腺素能刺激可增加 cAMP 的含量及触发造血干细胞进入细胞周期。作者研究了正常及受200伦照射的小鼠骨髓细胞对β-肾上腺素能刺激的影响,结果发现未照射的小鼠骨髓中 cAMP 的含量因腹 The proliferation and maturation of hematopoietic cells are controlled by many factors, of which certain hormones should be considered. Most of the role of hormones through the ring 3 ’, 5’-AMP (cAMP) as a medium. Other authors have demonstrated that β-adrenergic stimulation increases cAMP levels and triggers hematopoietic stem cell entry into the cell cycle. The authors studied the effects of normal and irradiated mouse bone marrow cells on β-adrenergic stimulation and found that the cAMP content in the non-irradiated mouse bone marrow was attributed to abdominal
