藻蓝蛋白对小鼠粒单系祖细胞生成的影响

EFFECT OF C - PHYCOCYANIN ON GRANULOPOIESIS AND MONOCYTOPOIESIS IN MICE

藻蓝蛋白(C—phycocyanin,C—PC)是从钝顶螺旋藻(Spirulina platensis)中分离、纯化所得。采用造血祖细胞体外培养技术,研究了C—PC对小鼠粒单系祖细胞生成的影响。实验结果表明,C—PC能够提高粒单系祖细胞(CFU—GM)的生成,亦能明显提高正常小鼠血清的集落刺激活性。C—PC体内或体外刺激制备的小鼠脾细胞条件培养液能明显增加CFU—GM的集落数。在有集落刺激因子(GM—CSF)存在时,体外加入C—PC培养粒单系祖细胞,C—PC能明显提高CFU—GM的集落生成率。

C - phycocyanin (C - PC) was isolated and purified from blue - green alga Spirulina platensis. By using the thechnique of culture of hemopoietic progenitor cell in vitro, we studied the effect of C -PC on granulopoiesis and monocytopoiesis in mice. The results indicate that C -PC can enhance the proliferation of CFU -GM, promote the granulopoiesis and monocytopoiesis in mice. The C -PC can markedly increase the colony stimulating activity of serum in normal mice. The prepared serum -free spleen cell conditioned media stimulated by C -PC in vivo and in vitro provided the only increase in CFU - GM colony formation. After in -vitro addition of C -PC in the presence of GM -CSF, there was a pronounced increase in the number of CFU -GM colonies.
