عنوان انگلیسی In vitro osteogenic induction of human adipose stem cells co-treated with betaine/osteogenesis differentiation medium
چکیده انگلیسی مقاله Human adipose-derived stem cells (hADSCs) are widely used in regenerative medicine and affected by many biochemical and biophysical stimuli in vivo. Betaine has been reported to be a type of osteogenic stimulating biochemical factor. This study aimed to investigate the effects of betaine; on osteogenic differentiation of cultured hADSCs in osteogenesis differentiation medium. Mesenchymal stem cells were extracted from women undergoing liposuction after obtaining written consent and cultured in vitro. The cells at passage 4 were confirmed by flow cytometry and differentiated into osteocytes and adipocytes. Experimental groups were the cells cultured in osteogenesis differentiation medium (control), cultured in α-MEM and 10% serum-containing Betaine (BET) ,and cultured in osteogenesis differentiation medium containing 10 mM Betaine (OD+BET). After 14 and 21 days of treatment, osteogenic differentiation and the expression of RUNX2 and OCN genes were assessed by qualitative and quantitative Alizarin red staining and real-time PCR. There were significant increases in the calcium matrix deposits, alkaline phosphatase activity ,and expression of RUNX2 and OCN genes in the OD+BET group compared to the BET group. At the end of day 14, the calcium matrix formation was significantly decreased the in BET group compared to the control. Treatment of hADSCs with Betaine, and osteogenesis differentiation medium leads to increased alkaline phosphatase activity, matrix calcium deposits and expression of RUNX2 and OCN genes and finally stimulated osteogenesis. This kind of treatment could be used to support bone regeneration in the future of tissue engineering.
