In situ tissue regeneration

Definition

In situ tissue regeneration refers to the process of repairing and regenerating tissue at the site of injury or damage, using the body's own biological mechanisms and cells. This method emphasizes the body's natural healing abilities and often involves the recruitment of resident stem cells and growth factors to promote tissue restoration without the need for extensive surgical intervention or implantation of artificial materials.
