Tissue regeneration is the process by which the body repairs or replaces damaged tissues. This can occur naturally, as seen in certain species like axolotls, which can regrow limbs, or through medical interventions that stimulate healing in humans. Regeneration involves complex biological mechanisms, including cell division and differentiation. Researchers study tissue regeneration to develop treatments for injuries and diseases. Techniques such as stem cell therapy and tissue engineering aim to enhance the body’s ability to heal itself. Understanding how regeneration works can lead to advancements in regenerative medicine, improving recovery outcomes for patients.
