Platelet rich plasma enhanced neuro-regeneration of human dental pulp stem cells and in rat spinal cord.

Background: Human dental pulp stem cells (hDPSCs) exhibit excellent differentiation potential and are capable of differentiating into several different cellular phenotypes, including neurons. Platelet-rich plasma (PRP) contains numerous growth factors that can stimulate stem cell differentiation. In this study, we investigated the potential stimulatory effects of PRP on neurogenic differentiation and anti-apoptosis of hDPSCs in injured spinal cords.
