Abstract:

BACKGROUND: Previous experiments have shown that improved platelet-rich plasma can promote the proliferation of human dental pulp cells in a concentration-dependent manner, particularly when the concentration is 10%.
OBJECTIVE: To investigate the effect of platelet-rich plasma at different concentrations on the proliferation and immunogenicity of human bone marrow mesenchymal stem cells.
METHODS: Human bone marrow mesenchymal stem cells from healthy donors were cultured and passaged for 3-4 passages, identified by flow cytometry and differentiation inductions. Platelet-rich plasma samples which were manufactured from the venous blood of the same donor were used for culturing human bone marrow mesenchymal stem cells. The proliferation of human bone marrow mesenchymal stem cells was measured by cell counting kit-8 method and the growth curves were drawn. The most suitable concentration of platelet-rich plasma was selected to culture human bone marrow mesenchymal stem cells for three generations and the Stro-1 expression rate on the surface of human bone marrow mesenchymal stem cells was determined through flow cytometry.
RESULTS AND CONCLUSION: Platelet-rich plasma at the concentration of 5%-10% evidently promoted the proliferation of human bone marrow mesenchymal stem cells on the 6th and 8th days. The most effective concentration to promote the proliferation was 10%. Platelet-rich plasma at the concentration of 10% still promoted the proliferation of human bone marrow mesenchymal stem cells on the 10th day, and maintained a better immunogenicity of human bone marrow mesenchymal stem cells compared to the control group. These findings indicate that platelet-rich plasma can promote the proliferation of human bone marrow mesenchymal stem cells in a concentration-dependent manner, and 10% platelet-rich plasma is better to maintain the immunogenicity of human bone marrow mesenchymal stem cells.
