Autologous cells are cells that are derived from the same individual who will receive them. This means that the cells are harvested from a patient’s own body, which reduces the risk of rejection by the immune system. Common sources for these cells include bone marrow, adipose tissue, or blood. These cells are often used in various medical treatments, including stem cell therapy and regenerative medicine. By using autologous cells, doctors aim to promote healing and repair damaged tissues while minimizing complications associated with donor cells.
