After 24 hours of culture in growth medium, BMMSCs were cultured in osteogenic differentiation medium (Cyagen Biosciences, Inc). %%EOF The statements, opinions and data contained in the journals are solely Within the range of 1.8-16.2 mM, increased concentrations of Ca ions had no effect on cell proliferation, but led … 0000001470 00000 n Consistently, our study also indicated that Curcumin treatment might enhance the osteogenic differentiation of hPDLSCs by the evidence of the Alizarin Red staining. h�b```b``�������� € "l@�������� ��"����j�Vw�޲��:f��6�*R�wݖ\5�F�;�?�ˈ�Ty2��d�!��������k�>�+�i��{�� @v�D�����_����5)Lp�~�g٪��s�7�T�Ue�g2�����ettt�]@���"����uq � W300f��� T!��`����91�;X��3�050;p0(w�^�O8Ÿ�%�͋�gс���6�6�0�0�0l``Z��� 4G�!�eM�[�������&��m��8�q � ����"�o4)bx�!U��� ��'�7�ϧ,@��E?1��1�x3@� �)n, (A) Gross appearance was observed with a camera; (B) Quantitative evaluation of Alizarin red staining in hPDLSCs. �Cw0�x�6��n�SxM�cƶ���ߛ�I��a�����¬V� �x�o������ML>�3b� ����Xu����Y�b?�$t���-�����jL�lO^,T�Y���k���|1��.�9C���1;�w�w�%�|�5��d.�7̨�o���t�]�4�]RXz,�͙sd�,lV��N�UfE���~����o��[�-�B��#�. Osteogenic differentiation of MSCs was detected and quantified by alizarin red S (ARS) staining for calcium deposition and alkaline phosphatase (ALP) activity, osteoprotegerin (OPG), and osteocalcin (OC) secretion measurements. After the overexpression or knockdown of miRNA-410-3p, we evaluated the changes in the osteogenic-like differentiation and osteogenesis-related protein by alizarin red staining and qPCR, respectively. (B) Alizarin red staining of hPDLSCs after 3 weeks of osteogenic induction (scale bar = 100 µm) (C) Oil red o staining of hPDLSCs after 3 weeks of adipogenic differentiation (scale bar = 50 µm). Alizarin red staining was used to estimate the deposits of calcium aggregates. Filter the solution through 0.22 µ membrane and store at 4oC in dark. Further, the expression levels of two osteogenic differentiation markers, osteocalcin and osteopontin, were upregulated by CNR2 agonists, and downregulated by 3-MA (Fig. See further details. Alizarin Red S is an anthraquinone dye used to stain for calcium deposits, which are indicators of mature osteocytes. Alizarin red staining method, Alkaline phosphatase (ALP) activity assay, and quantitative real-time PCR analysis were performed to assess hMSSM-derived cells osteogenic differentiation. (C) The MSCs were cultured for 2 weeks in osteogenic medium, and stained with alizarin red S stain to identify differentiation. Moreover, MSCs are known to sensitively respond to topological and mechanical cues, and thus differentiation in 3D can be … Similar to mesenchymal stem cells, the induction and differentiation of hPDLSCs are usually marked by the appearance of certain macromolecules and characteristic protein substrates ( Chou & Kuo-Chen, 2016 ). differentiated in commonly applied serum-containing osteogenic medium for 35 days. Alizarin Red S staining of osteoblasts (12 well plate) 1. Mesenchymal stem cells (MSCs) are adult stem cells that are able to give rise to bone, cartilage and fat cells . 903 0 obj <>stream Data were statistically processed. 0000000016 00000 n No lipid droplets were observed in the undifferentiated MSCs (magnification, ×200). Int. Flow cytometry, Alizarin Red staining and Oil Red O staining were applied to confirm the stemness of the stem cells. osteogenic induction when using mouse ADSCs. Sci.
