Cell therapy is a revolutionary medical approach. It involves the use of living cells to treat diseases and repair damaged tissues. In this therapy, specific types of cells, such as stem cells or immune cells, are manipulated and administered to patients. Stem cells have the potential to differentiate into various cell types and can be used to regenerate damaged organs or tissues. Immune cells can be engineered to target cancer cells more effectively. Cell therapy holds promise for treating a wide range of conditions, including cancer, cardiovascular diseases, neurological disorders, and autoimmune diseases. However, it also poses challenges such as ensuring the safety and efficacy of the cells and developing standardized procedures. Research in cell therapy is ongoing, and it is expected to play an increasingly important role in the future of medicine.
