Abstract:
BACKGROUND AND OBJECTIVES: One of the most cellular source used for cartilage tissue engineering are mesenchymal stem cells (MSCs). In present study, human MSCs were used as cellular source. Since scaffold plays an important role in tissue engineering the aim of this study is to assess fibrin scaffold ability in chondrogenic differentiation of adipose-derived mesenchymal stem cells (ADMSCs). METHODS: ADMSCs were isolated and cultured in DMEM medium supplemented with 10% FBS. Also ADMSCs expanded and characterised by flow cytometry. ADMSCs expressed CD44, CD90, CD105 but not CD34. After trypsinization, cells were entered within the fibrin scaffold. Then, chondrogenic medium was added to the scaffold. Seven days after cell culture, cell viability and proliferation were assessed by MTT test. Finally, 14 days after the ending of chondrogenic differentiation, analysis of chondrogenic genes expression was evaluated by RT-PCR and Real time PCR. Also, formation and development of chondrocyte cells was analysed by histological and immunohistochemistry evaluations. RESULTS: Viability and proliferation as well as chondrogenic genes expression within fibrin scaffold increased significantly compared with control group (cells free scaffold). Also, histological and immunohistochemistry evaluation showed that chondrocyte cells and collagen type II are formed on fibrin scaffold. CONCLUSIONS: Fibrin is a suitable scaffold for chondrogenic differentiation of ADMSCs.
