What is the role of growth factors in wound healing?

The role of growth factors in wound healing is primarily to stimulate cell proliferation and tissue formation. Growth factors are proteins that play a crucial role in various cellular processes associated with healing. When a wound occurs, growth factors are released to signal cells to migrate to the area and divide, promoting new tissue formation and aiding in the repair of damaged skin and other tissues.

These proteins also help in the formation of new blood vessels (angiogenesis) and the synthesis of extracellular matrix components that give structure to the healing tissue. By fostering these cellular activities, growth factors facilitate an optimal progression through the stages of wound healing, leading to more effective recovery and closure of wounds.
