Tissue repair is a research area within biological and medical sciences that focuses on the process by which the body repairs and regenerates damaged or injured tissues. This field explores the mechanisms involved in tissue healing, including the role of immune cells, growth factors, and stem cells in promoting tissue regeneration. Scientists in this area aim to understand how tissues repair themselves under normal conditions, as well as how this process may be impaired in various diseases or injuries. Ultimately, the goal of tissue repair research is to develop new therapeutic strategies and interventions to enhance tissue regeneration and improve patient outcomes.
