Abstract:
Platelet-rich plasma (PRP) is an autologous concentration of platelets in concentrated plasma, which is extensively used to promote soft and hard tissue healing. The significance behind its use refers to the abundance of growth factors present in a well-prepared PRP concentrate. These growth factors enhance the rate and quality of wound healing by different mechanisms. The objective of this review article is to explain the biological aspect of hard and soft tissue healing by application of PRP in conjunctions with its molecular basis.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
