The Potential Alteration of Their Osteogenesis and Adipocyte Differentiation in Bone Marrow Mesenchymal Stem Cells from Mice with Immune-mediated Aplastic Anemia / 浙江中医药大学学报

[Objective]To explore the potential alteration of their osteogenesis and adipocyte differentiation in bone marrow mesenchymal stems cells from mice with immune-mediated aplastic anemia.[Methods]Balb/c mice model of immune-mediated aplastic anemia was established by radiation with sublethal dose of 60Co following the intravenously infusion lymphocytes of DAB/2 mice.The culture of the MSC and CFU-F and pathological examination of bone marrow were carried out 15 days later.The amount of calcium node and the frequency of adipocyte differentiation were evaluated respectively by alizarin red and oil red O.[Result]The number of CFU-F and the number of calcium node in model mice decreased more greatly than normal mice,but the ferenqucy of adipocyte differentiation was more increased greatly in model mice than normal mice;the pathological examination showed in the model mice,the hematopoietic structure was destroyed and filled with abundant adipocyte.[Conclusion]The potention of osteogenesis and adipocyte differentiation was altered in the mice with immune-mediated aplastic anemia.

Effect of Hongqu on induction differentiation of bone marrow stromal cells to osteoblasts in rat / 中华中医药杂志

Objective: To study the effect of Chinese medicinal herb Hongqu on induction differentiation of bone marrow stromal cells to osteoblasts.Methods:60 SD rats were divided randomly into 6 groups: blank control group,Low,medium and high dose of Hongqu groups,Provastain group,Premarin group.Each group was given distilled water,Hongqu extraction,Provastain solution,and Premarin solution through intragastric administration.10 days later,killed the rats and took the rats’ blood to prepared medicated serum.Meanwhile,the bone marrow stromal cells which comes from femur and tibia of the 4-5 week’s rats were cultured in medicated serum culture-medium,and MTT,para-nitro-pheneye phosphate,and the tinctorial method of alizarin Bordeaux were used to observe the effect of Hongqu on such aspects as the proliferation,ALP expression,and mineralization tuberculation of marrow stromal cells induction differentiation to osteoblasts.Results: Mmedicated serum of Hongqucould obviously increace the quantity of marrow stromal cells induction differentiation to osteoblasts,the level of the ALP expression and mineralization tuberculation(P
