Abstract:

BACKGROUND: Hypoxic death limits application of cells in transplantation and tissue regeneration.
OBJECTIVE: To investigate the protective effects of mangiferin on bone marrow-derived mesenchymal stem cells against hypoxia injury-induced apoptosis resulted from cobalt chloride.
METHODS: Rat bone marrow-derived mesenchymal stem cells were in vitro cultured and hypoxia cell model was established by cobalt chloride. Model cells were treated with mangiferin. Protective effects of mangiferin were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; cell apoptosis and mitochondrial membrane potential were detected using flow cytometry.  
RESULTS AND CONCLUSION: Cobalt chloride significantly inhibited growth of bone marrow-derived mesenchymal stem cells in a dose-dependent manner. The apoptosis rate of cells was (42.49±3.96)% after treated with 200 μmol/L cobalt chloride for 12 hours, (46.37±4.49)% after treated for 24 hours. With increasing concentration of mangiferin, apoptosis of bone marrow-derived mesenchymal stem cells in hypoxic model was gradually reduced (P < 0.01), indicating that mangiferin has a protective effect in a concentration-dependent manner on rat bone marrow-derived mesenchymal stem cells in hypoxic injury. Cobalt chloride can induce hypoxic model successfully in bone marrow-derived mesenchymal stem cells. There are some advantages of accurate dose control, no special equipment requirements, and easy operation. Mangiferin can effectively inhibit bone marrow-derived mesenchymal stem cells apoptosis under hypoxic injury.
