Experimental Study On Biocompatibility In The Three-Dimensional Porous BG/Osteoblasts (Differentiated From MSCs)

BackgroundAutologous, allogeneic bone and artificial materials had been used in clinical for bone defects caused by wound and various kinds of disease , but there's demerit such as anatomic structure, supply border defect, immunization exclude and hard to mix together with body. It's possible to avoid defect of tradition cure method, and solve the difficulty of artificial bone of repair and rebuild as the development of tissue engineering technology. There need great quantity of seed cells and fine cytoskeleton materials for tissue engineering to satisfy the request of engineering tissue of organ for building and moulding. Culture of seed cells and suitable materials is a basic element of tissue engineering, cells mainly come from self-cell, variant of the same homogeneity, cells of heterogeneity, and so on. Self-histiocyte is the first choice. Owing to tissue engineering often demands high concentration of inoculation cells, self-histiocyte has some questions about quantity of localization, passed culture for long period of time and function aging.The engineering of stem cells was to regeneration of mesenchymal tissues such as bone, cartilage, skin as well as hematopoietic and immunity tissue by using tissue engineering technique get across to separation, purification, direct inducement, differentiation, a great deal of expand increase and conformity construct in mesenchymal progenitor cells in vitro. Study on the progenitor of tissue engineering which have important role and deeply effect on the repair or replace of tissue and organ in the future. Compared with traditional tissue engineering, tissue engineering have obvious difference and advantage over its sourse of tissue and organic cells,...
