Effects of Different Extracts of Jianpi Huogu Formula on Proliferation and Differentiation of Bone Marrow Mesenchymal Stem Cells / 中国中医药信息杂志

ABSTRACT

Objective To observe effects of different extracts of Jianpi Huogu Formula (JPHGF) on proliferation and differentiation of bone marrow mesenchymal stem cell (BMSCs). Methods Whole bone marrow adherent was used to screen, culture, and isolate BMSCs. Extracts from different parts (water, chloroform, ethyl acetate and n-butanol parts) of JPHGF were administrated for a certain time. MTS was used to detent cell proliferation;ALP staining was used to detect ALP activity;ARS staining was used to detect the formation of calcium nodules;oil red O staining was used to detect fat cell formation. Results Extracts from different parts of JPHGF could promote cell proliferation of BMSCs in different levels, followed by its strength in water, chloroform, ethyl acetate, and n-butanol parts;ALP staining results showed that the intensity of ALP expression of the order is water, acetic acid ethyl, chloroform and n-butanol parts;in promoting the formation of calcium nodules, ARS staining results showed that its intensity were water, chloroform, ethyl acetate, and n-butanol parts;oil red O staining results showed that inhibition intensity of fat cells interaction strength was formed from ethyl acetate, water, chloroform to n-butanol parts. Conclusion Extracts from different parts of JPHGF have different effects on BMSCs proliferation and differentiation. Water extraction has the strongest osteogenic differentiation and proliferation, and ethyl acetate has the best effect on the inhibition of cell formation.
