Tissue repair refers to the process by which damaged or injured tissues in the body are repaired and restored back to their normal function. This can occur through various mechanisms, including cell division (regeneration), migration of cells from other parts of the body (migration) or by forming new blood vessels (angiogenesis). The process involves a complex interplay between different types of cells, growth factors, and extracellular matrix components. Tissue repair is essential for maintaining the integrity and function of various organs and tissues in the body, and its proper regulation is crucial for overall health and well-being.
