【Abstract】 The effects of >10?kD component of serum free conditioned medium from murine bone marrow derived endothelial cell line on the formation of CFU GM and HPP CFC were investigated. We found that >10?kD component alone could stimulate CFU GM colony formation in dose dependent. Above 10?kD component supplemented with GM CSF not only resulted in significant increase of CFU GM as compared with >10?kD or GM CSF alone, but also could stimulate HPP CFC formation. The effect of >10?kD component on the formation of HPP CFC was also in dose dependent. The component above 10?kD combined with IL 3, IL 6, EPO, SCF or GM CSF further enhanced HPP CFC colony formation. The results suggest that >10?kD component may be used as the substitutes of hematopoietic growth factors to stimulate the formation of CFU GM and HPP CFC. [更多还原
