Growth factor receptors are specialized proteins located on the surface of cells. They play a crucial role in cell communication by binding to specific molecules called growth factors. When a growth factor attaches to its receptor, it triggers a series of events inside the cell that can lead to growth, division, or other important functions. These receptors are essential for various biological processes, including development, healing, and tissue maintenance. Abnormalities in growth factor receptors can lead to diseases, such as cancer, where cells may grow uncontrollably. Understanding these receptors is vital for developing targeted therapies in medicine, particularly in oncology and regenerative medicine.
