Platelet-rich plasma (PRP) contains various growth factors such as platelet-derived growth factor (PDGF), transforming growth factor (TGF), vascular endothelial growth factor (VEGF), and others. These growth factors play a crucial role in tissue repair, regeneration, and healing. When PRP is injected or applied to a specific area, these growth factors stimulate cell growth, and collagen production, and promote the regeneration of tissues, aiding in the healing process.
