Results High homogenous hMSCs were obtained and after co-culture for 5 d with osteoblasts, they fused to form multinuclear cell clusters in micrograph and were postive in TRAP staining. Conclusion The co-culture system method is successful.

结果：体外分离、培养的hMSCs具有独特的细胞免疫学表型，即CD73和CD105阳性， CD34和CD45 阴性。hMSCs与成骨细胞共同培养5 d后，即可见单个核细胞融合成多核细胞，TRAP 染色可见多数细胞胞浆呈酒红色，为诱导成功的破骨细胞。

Results: Proliferation of K562 cells was significantly inhibited by naringenin and the IC50 at 24, 48 and 72h were 455, 225 and 175μmol/L respectively. Cell growth inhibition and apoptosis were observed under light microscope and transmission electron microscope. Observation by flow cytometry indicated that K562 cells were blocked in G0/G1 phase of cell cycle in naringenin group, and S phase cells were remarkably decreased. PCNA expression in each treatment group was remarkably less than in control group.
