Understanding Stem Cells: A Primer
To demystify the subject, Dr. Hariri offers a straightforward explanation of stem cells. At conception, a single totipotent stem cell forms, which has the remarkable capability to develop into every cell type in the body, from skin to neurons. These stem cells not only define the initial stages of life but also persist in various tissues, acting as the body’s natural repair kit capable of self-renewal and specialization as needed.
This process, known as differentiation, allows stem cells to adapt to their environment, such as becoming liver or heart cells depending on the body's demands. Dr. Hariri articulates the analogy of a handyman—a well-stocked toolbelt allows for effective repairs.
