dc.description.abstractObjective: This study evaluated in vitro differentiation of mesenchymal stromal cells isolated from bone marrow, in tenocytes after treatment with bovine tendon extract. Methods: Bovine tendons were used for preparation of the extract and were stored at −80 ◦C. Mesenchymal stromal cells from the bone marrow of three donors were used for cytotoxicity tests by means of MTT and cell differentiation by means of qPCR. Results: The data showed that mesenchymal stromal cells from bone marrow treated for up to 21 days in the presence of bovine tendon extract diluted at diminishing concentrations (1:10, 1:50 and 1:250) promoted activation of biglycan, collagen type I and fibromodulin expression. Conclusion: Our results show that bovine tendon extract is capable of promoting differentiation of bone marrow stromal cells in tenocytes. Objetivo: O estudo avalia a diferenciação in vitro das células mesenquimais isoladas do estroma da medula óssea em tenócitos após tratamento com extrato de tendão bovino. Método: Tendões bovinos foram usados para confecção do extrato e estocados a −80 ◦C. Células mesenquimais do estroma da medula óssea (BMSCs) de três doadores foram usadas para os testes de citotoxicidade por MTT e diferenciação celular por qPCR. Resultado: Os dados mostram que células mesenquimais do estroma da medula óssea tratadas por até 21 dias em presença do extrato de tendão bovino diluído em concentrações crescentes (1:10, 1:50 e 1:250) promovem a ativação da expressão de biglican, colágeno tipo I e fibromodulina. Conclusão: Nossos resultados mostram que o extrato de tendão bovino é capaz de promover a diferenciação das BMSCs em tenócitos.
