متن کاملThe proliferation of fibroblast cells on the polycaprolactane-chitosan-tannic acid scaffold
Background and Objective: Tissue engineering is a new method for replacing damaged tissue components in order to improve its function. In this method, a porous scaffold mixed with polysaccharide and synthetic antioxidants is first produced and then stem cells are cultured inside it. In this study, the polycaprolactane-chitosan-tannic acid scaffold was used to reproduce the amount Fibroblast cel...
