Results The latent phase of the primary culture cells was 5-9 days, followed by 11-16 days of logarithmical proliferation; the plateau began at day 18-20. The subcultures showed 12-24 hours of latent phase, followed by 7-10 days of logarithmical proliferation, then entered the plateau (11-13 days). The hMSC expressed positive CD44 unanimously, but don′t expressed CD45. Low concentration of bFGF (10 μg·L-1) could stimulate the proliferation of hMSC significantly (P.05); while 25-100 μg·L-1 of bFGF could inhibit the ALP activity.

结果：原代培养细胞生长潜伏期5~9 d，对数增殖期11~16 d，生长平台期18~20 d；传代培养细胞生长潜伏期12~24 h，对数增殖期为7~10 d，11~13 d进入细胞生长平台期。hMSC均一表达CD44，不表达CD45.bFGF在较低浓度（10 μg·L-1）时即有显著的促进hMSC增殖的作用（P.05）， bFGF在25~100 μg·L-1对hMSC的ALP活性有较显著的抑制作用。

The application of ionic liquids aqueous solutions as solvents in the microwave-assisted extraction technique was developed for the extraction of lycorine, lycoramine and galanthamine from Lycoris. Effects of different ionic liquids and the concentration of selected ionic liquids on MAE were investigated, and tradition organic solvent and extraction techniques were compared.
