چکیده انگلیسی

ObjectiveThis study evaluated in vitro differentiation of mesenchymal stromal cells isolated from bone marrow, in tenocytes after treatment with bovine tendon extract.MethodsBovine 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.ResultsThe 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.ConclusionOur results show that bovine tendon extract is capable of promoting differentiation of bone marrow stromal cells in tenocytes.

ResumoObjetivoO estudo avalia a diferenciação in vitro das células mesenquimais isoladas do estroma da medula óssea em tenócitos após tratamento com extrato de tendão bovino.MétodosTendões 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.ResultadosOs 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.ConclusãoNossos resultados mostram que o extrato de tendão bovino é capaz de promover a diferenciação das BMSCs em tenócitos.
