Abstract:

BACKGROUND: Platelet-rich plasma, when activated, could secret multiple growth factors which may promote the proliferation and differentiation of bone marrow-derived mesenchymal stem cells.
OBJECTIVE: To explore the effect of activated autologous platelet-rich plasma on the chondrogenic differentiation of rabbit bone marrow-derived mesenchymal stem cells in vitro.
METHODS: Rabbit bone marrow-derived mesenchymal stem cells were isolated using the whole bone marrow adherence method. Passage 3 bone marrow-derived mesenchymal stem cells were in vitro cultured with 10% activated autologous platelet-rich plasma and 10% fetal bovine serum separately. Chondrogenic differentiation of rabbit bone marrow-derived mesenchymal stem cells in vitro was observed.
RESULTS AND CONCLUSION: Bone marrow-derived mesenchymal stem cells were successfully isolated and exhibited a long-shuttle-shaped appearance. Cells grew faster when passaged. Immunofluorescence staining showed that after induced by activated autologous platelet-rich plasma, bone marrow-derived mesenchymal stem cells exhibited type Ⅱ collagen expression. Quantitative real-time PCR analysis showed that the expression of α1 chain of type Ⅱ collagen and aggrecan mRNA was significantly up regulated in the bone marrow-derived mesenchymal stem cells induced by activated autologous platelet-rich plasma than in the cells induced by fetal bovine serum (P < 0.01). Our findings in this study suggested that activated autologous platelet-rich plasma can promote the chondrogenic differentiation of rabbit bone marrow-derived mesenchymal stem cells in vitro.
