Tissue repair at wound sites begins with clot formation, and subsequently platelet degranulation with the release
of platelet growth factors, which are necessary and well-regulated processes to achieve wound healing. Plateletderived
growth factors are biologically active substances that enhance tissue repair mechanisms, such as chemotaxis, cell
proliferation, angiogenesis, extracellular matrix deposition, and remodeling. This review describes the biological background
and results on the topical use of autologous platelet-rich plasma and platelet gel in gynecologic, cardiac, and general
surgical procedures, including chronic wound management and soft-tissue injuries.
Keywords: Platelets, platelet-rich plasma (PRP), platelet gel (PG), growth factors, wound healing, cardiac surgery, gynecology,
general surgery, adipose graft.
