ABSTRACT
Aim To observe mesenchymal stem cell differentiation into osteoblast induced by TSPG, and explore how TSPG enhances the promotion of hemato-poiesis of osteoblast differentiation from mesenchymal stem cell. Methods MSCs were cultured by TSPG combined with osteoinductive medium. The cellular vi-ability of proliferation was detected with MTT assay. The content of alkaline phosphatase in the cultural su-pernatant was tested with pNPP assay. The ability of MSCs to form calcium nodes was also observed after a-lizarin red stain. The protein expression of RUNX2 was analyzed with Western blot. The content of cytokines associated with hematopoiesis was tested with Elisa as-say. The ability of promoting hematopoiesis was detec-ted with hematopoietic colony forming assay. Results Both MTT and pNPP assay showed that optical den-sity ( OD) values were increased in response to TSPG treatment in a dose-dependent manner. The mineraliza-tion formation ability was enhanced with TSPG-treat-ment. Meanwhile, the expression of RUNX2 protein was up-regulated in TSPG-treated cell. Moreover, the content of cytokines associated with hematopoiesis and the number of hematopoietic progenitor colony were in-creased by TSPG-treatment compared with the control group. Conclusion TSPG could induce MSCs differ-entiation in to osteoblast and enhance the effect of oste-oblast differentiation from MSCs on promoting hemato-poiesis.
