Therapeutic cloning is a scientific process that involves creating cloned cells for medical purposes. It typically uses a technique called somatic cell nuclear transfer, where the nucleus of a donor cell is inserted into an egg cell that has had its nucleus removed. This process can produce stem cells that are genetically identical to the donor, which can then be used to generate tissues or organs for transplantation. The primary goal of therapeutic cloning is to develop treatments for various diseases, such as Parkinson's disease, diabetes, and spinal cord injuries. By using the patient's own cells, the risk of rejection by the immune system is minimized, making it a promising area of research in regenerative medicine.
