摘　　要：目的研究PINCH-1因子在急性白血病骨髓基质细胞中的表达及意义。方法培养骨髓基质细胞,用West-ern-blotting和RT-PCR观察PINCH-1 mRNA和蛋白的表达情况;进行免疫细胞化学和免疫荧光染色,观察PINCH-1蛋白的表达及其在细胞内的分布情况。结果在急性淋巴细胞白血病和急性髓系白血病患者骨髓基质细胞中,PINCH-1在mRNA水平和蛋白水平均比正常骨髓基质细胞增高(P<0.01);急性淋巴白血病与急性髓系白血病之间PINCH-1蛋白的表达有显著差异(P<0.01),但mRNA表达无明显差别。结论PINCH-1在急性白血病骨髓基质细胞表达明显高于正常骨髓基质细胞,可能与急性白血病发生发展相关。Objective To investigate the expression of PINCH-1 in acute leukemia bone marrow stromal cells and its significance. Methods Bone marrow stromal cell were cultivated. The expression of PINCH-1 mRNA and protein were observed by RT-PCR and Western blotting; the distribution and expression of PINCH-1 protein in target cells were observed by immunocytochemistry and immunofluorescence technique. Results The levels of PINCH-1 mRNA and protein were significant higher in bone marrow stromal cells of patients with a...
