Objective To explore the qi-tonifying and blood-activating Chinese herb serum on pro-liferation of SD rat bone marrow mesenchymal stem cells ( BMSCs) in vitro. Methods Rat BMSCs were i-solated from rat bone marrow and expanded by whole bone marrow adherent culture method in vitro, collect-ed blank serum of rat as control group and serum from qi-tonifying Chinese herb, blood-activating Chinese herb, qi-tonifying & blood-activating Chinese herb gavaged rats. BMSCs of the third generation were cul-tured in vitro with 10% concentrations of these four kinds of medicated serum at 37 ℃ and 5% CO2 incu-bator respectively. Flow cytometry was used for the identification of BMSCs and the proliferation of BMSCs was observed by MTT method and drew the growth curve. Results The BMSCs were obtained by whole bone marrow adherent culture method. The membranes of third generation of BMSCs were positive for CD44 and CD106 and negative for CD45 and CD34 detected by flow cytometry. The results showed that BMSCs grown rapidly compared to the day before it selves to the 2nd, 4th, and 5th days, the difference was signifi-cantly ( P<0. 05 ) . The cell growth of the blood-activating Chinese herb serum group and qi-tonifying &blood-activating Chinese herb serum group showed a downward trend, while the cell growth of the other three groups reached peak on the 6th day, but still had differences compared to the 5th day (P<0. 05), and declined on the 7th day. The removed baseline proliferation rate of BMSCs had no differences comparison a-mong groups at 2nd day, but the removed baseline proliferation rate of BMSCs in blood-activating Chinese herb serum group reached maximum (71. 39 ± 4. 98%), but no differences compared with the other three groups (P>0. 05). Compared with the other three groups, the removed baseline proliferation rate of qi-tonifying & blood-activating Chinese herb serum group was the largest ( 66. 40 ± 1. 47%) ( P<0. 01 ) on the 4th and 6th days, followed by blood-activating Chinese herb serum group. The removed baseline prolifer-ation rate of qi-tonifying Chinese herb serum group was the highest on the 6th day, followed by qi-tonifying&blood-activating Chinese herb serum group and blood-activating Chinese herb serum group. Conclusion BMSCs of SD rat isolation and cultivation by whole bone marrow adherent culture method could steadily express the bone mesenchymal stem cells surface markers and cells morphology. Qi-tonifying&blood-acti-vating Chinese herb serum has the greatest effect on the proliferation of cultured BMSCs; blood-activating Chinese herb serum motivates cell proliferation earliest; qi-tonifying Chinese herb serum has the longest effects on cell proliferation.
