Objective:To investigate the capability of tooth tissue-bone complex-like structure in vivo formed by rDECs+rDMCs-nHAC/PLA compounds induced by different growth factors.Methods:Rat dental epithelial cells(rDECs)and rat dental mesenchymal cells(rDMCs)were isolated,cultured and identified.The cell-scaffold compounds were transplanted into athymic mice subcutaneously and taken out after 3or 5 months.The capability of tooth tissue-bone complex-like structure formed by the graftswas detected.Results:BothrDECs an...
