BACKGROUND: Tendon repair requires a sequence of medical procedures such as physical modalities, tissue engineering, growth factors, and mechanical stimulation. Previous studies have shown that using of PRP is effective in tendon healing. OBJECTIVES: The purpose of this study was to investigate the differentiation effect of PRCR on mesenchymal stem cells extracted from rabbits’ bone marrow. METHODS: Mesenchymal stem cells were extracted from bone marrow (BM-MSCs) of 10 New Zealand white rabbits. The cells were then examined both flow cytometrically and morphologically. Afterwards, the cells received treatment using PRCR. Finally, the markers indicating tenocytes were analyzed through the method of Real-Time PCR. RESULTS: Investigating the differences between differentiated cells and undifferentiated stem cells (BM-MSCs) regarding the expression of four genes including Scx, Tnmd, Col I, and Tenascin C revealed that the level of expression in all the four genes was significantly enhanced after receiving PRCR- mediated treatment. CONCLUSIONS: BM-MSCs treated with PRCR express high levels of tendon-related genes and undergo differentiation into tenocyte-like cells.
