Stem cell-based regenerative therapies harness the unique ability of stem cells to repair, replace, or regenerate damaged tissues and organs. These therapies hold promise for treating a wide range of conditions, including neurodegenerative diseases, heart failure, diabetes, and spinal cord injuries. By promoting tissue regeneration and modulating immune responses, stem cells offer a powerful tool in modern medicine. Ongoing clinical trials and research are expanding their therapeutic potential while ensuring safety and efficacy.
