AIM: To investigate the effects of human umbilical cord-derived mesenchymal stem cells ( hUC-MSCs) on the proliferation and migration of osteosarcoma cells ( Saos-2 ) and the underlying molecular mechanism. METHODS:hUC-MSCs were isolated and cultured by tissue explants adherent method.The cell surface markers on hUC-MSCs were identified by flow cytometry.The effects of conditioned medium ( CM) from hUC-MSCs ( hUC-MSCs-CM) , re-combinant human interleukin-6 (rhIL-6) and IL-6 neutralizing antibody on the proliferation of Saos-2 cells were detected by CCK-8 assay and cell counting.IL-6 secretion of hUC-MSCs was assayed by ELISA.RT-PCR was used to assess the tran-scription level of proliferation-related genes proliferating cell nuclear antigen ( PCNA) , cyclin D1 and survivin.The migra-tion potential of hUC-MSCs and Saos-2 cells was measured by Transwell assay.RESULTS:hUC-MSCs migrated to Saos-2 cells.hUC-MSCs-CM contained a high concentration of IL-6, up to (1 835.5 ±134.1) ng/L.hUC-MSCs-CM and rhIL-6 promoted the proliferation and migration of Saos-2 cells.Addition of neutralizing antibody against IL-6 in the hUC-MSCs-CM impaired this proliferation and migration of Saos-2 cells.The mRNA expression of PCNA, cyclin D1 and survivin was up-regulated by hUC-MSCs-CM and rhIL-6, while this effect was dramatically attenuated by treatment with IL-6 neutralizing antibody.CONCLUSION:hUC-MSCs migrate to osteosarcoma cells and promote the proliferation and migration of osteo-sarcoma cells through secreting IL-6 in vitro.

Objective To evaluate the anti-tumor effects of chemotherapeutic drugs on human gastric cancer cells. Methods From April 2006 to February 2007, 84 patients with gastric cancer underwent surgical resection at General Hospital of Jinan Military Command. The single-cell suspension of these gastric tumors was prepared. The gastric cancer cells were cultured with hydroxycamptothecin, cisplatin, adriamycin, 5-fluorouracil and mitomycin for 48 hours, and changes in activity of the gastric cancer cells were studied via MTT assay. The expression of survivin and PTEN was detected by immunohistochemistry. Data were analyzed by chi-square test, rank sum test and Fisher exact test. Results The anti-tumor effects of different chemotherapeutic drugs were different, and the poorly-differentiated gastric cancer cells were more sensitive to the cytotoxic effects of chemotherapeutic drugs than the well-differentiated gastric cancer cells. The expression levels of survivin in the signet ring cell carcinoma, mucinous adenocarcinoma and other poorly-differentiated adenocarcinoma were significantly higher than those in papillary carcinoma and tubular carcinoma (χ~2 = 10.625, P <0.05), while the expression of PTEN was inverse to that of survivin (χ~2 = 6.060, P < 0.05). The expression of survivin was related to the resistance of the gastric cancer cells to 5-fluorouracil and adriamycin (χ~2 = 6.609, 6.350, P < 0.05). Conclusions In vitro chemosensitivity assay is helpful in selecting the chemotherapeutic regimen for specific types of gastric cancer. Survivin may contribute to the chemotherapy-resistance of certain types of gastric cancer cells, and its expression is related to that of PTEN.
