骨髓(BM)及其来源的细胞在放射性急性胃肠道综合征中的作用存在争议。在这里,我们使用骨髓移植(BMT)、全身照射(TBI)和腹部照射(ABI)模型来证明BM来源的细胞在急性GI损伤和恢复中的作用非常有限。与接受WT BM的小鼠相比,接受抗辐射的PUMA KO小鼠的BM在15或12GyTBI后对隐窝和绒毛的损伤或恢复没有保护作用,但在12GyTBI后有显著的存活益处。Puma KO BM可显著保护IR后供者来源的泛肠造血细胞(CD45+)和内皮细胞(CD105+)。我们进一步证明,PUMA KO BM不能提高辐射敏感的p21KO受体小鼠的动物存活率或隐窝再生。这些发现清楚地将辐射对肠上皮细胞的影响与剂量依赖的急性辐射毒性中对骨髓和内皮细胞的影响区分开来。
The role of bone marrow (BM) and BM-derived cells in radiation-induced acute gastrointestinal (GI) syndrome is controversial. Here we use bone marrow transplantation (BMT), total body irradiation (TBI) and abdominal irradiation (ABI) models to demonstrate a very limited, if any, role of BM-derived cells in acute GI injury and recovery. Compared with WT BM recipients, mice receiving BM from radiation-resistant PUMA KO mice show no protection from crypt and villus injury or recovery after 15 or 12 Gy TBI, but have a significant survival benefit at 12 Gy TBI. PUMA KO BM significantly protects donor-derived pan-intestinal haematopoietic (CD45 +) and endothelial (CD105 +) cells after IR. We further show that PUMA KO BM fails to enhance animal survival or crypt regeneration in radiosensitive p21 KO-recipient mice. These findings clearly separate the effects of radiation on the intestinal epithelium from those on the BM and endothelial cells in dose-dependent acute radiation toxicity.
