Filed: 2018-10-12
Abstract: The present invention relates to a method for differentiating mesenchymal stem cells to bone cells, comprising a step of culturing mesenchymal stem cells on a scaffold on which multichannel calcium phosphate granules are formed. In particular, it was confirmed that the mesenchymal stem cells cultured on the scaffold on which the multichannel calcium phosphate granules are formed, are securely fixed to scaffold surface and sides, and then penetrate the channels to propagate. Also, it was confirmed that when mesenchymal stem cells are cultured in osteogenesis-inducing conditions by using the scaffold on which the multichannel calcium phosphate granules are formed, alkaline phostapase (ALP) activity and mineralization were increased and also, the expressions of mRNA and protein of bone cell markers, such as ALP, COL1, osteopontin (OPN), and runt-associated transcription factor 2 (Runx2) were increased, thereby inducing the differentiation to bone cells. Thus, the scaffold on which the multichannel calcium phosphate granules are formed may be used as a scaffold for differentiation of mesenchymal stem cells and bone restoration.
