We transplanted adult whole bone marrow prelabeled with bromodeoxyuridine (BrdU) into the ischemic boundary zone of the adult rat brain at 1 day after 2 h of middle cerebral artery occlusion (MCAo). Approximately 3.3% of 10(6) transplanted bone marrow cells were BrdU reactive at 14 days after MCAo. BrdU-reactive cells expressed neuronal and astrocytic proteins, neuronal nuclei protein (NeuN, 1%), and glial fibrillary acidic protein (GFAP, 5%) immunoreactivities, respectively. In addition, bone marrow transplantation promoted proliferation of ependymal and subependymal cells, identified by nestin (a neuroepithelial stem cell marker), within the ventricular zone and subventricular zone (VZ/SVZ). These data suggest that intracerebral transplantation of bone marrow could potentially be used to induce plasticity in ischemic brain.
在大脑中动脉闭塞(MCAo)2小时后1天,我们将预先用溴脱氧尿苷(BrdU)标记的成年大鼠全骨髓移植到成年大鼠脑缺血边界区。在MCAo后14天,约3.3%的10(6)个移植骨髓细胞呈BrdU反应性。BrdU反应性细胞分别表达神经元和星形胶质细胞蛋白、神经元核蛋白(NeuN,1%)和胶质纤维酸性蛋白(GFAP,5%)免疫反应性。此外,骨髓移植促进了脑室区和室下区(VZ/SVZ)中由巢蛋白(一种神经上皮干细胞标志物)鉴定的室管膜和室管膜下细胞的增殖。这些数据表明,骨髓脑内移植可能潜在地用于诱导缺血性脑的可塑性。
