Stem cell therapy marks a groundbreaking medical shift, offering innovative treatments for neurological disorders and heart disease. This guide outlines the therapy’s timeline, covering its history, current uses, and future potential.
Introduction to Stem Cell Therapy
Stem cell therapy leverages the body’s foundational cells to repair or regenerate damaged tissues and organs. It primarily uses two types of stem cells: pluripotent stem cells, capable of becoming any cell type, and multipotent mesenchymal stem cells, derived from adult tissues with a more limited differentiation scope.
