Definition of Stem Cell: In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can change into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. From: Atala A, Lanza R (2012). Handbook of Stem Cells. Academic Press. ISBN 978-0-12-385943-3.
The human body is capable of remarkable regeneration when properly stimulated, and few stimuli are as powerful as exercise. While modern stem cell clinics—particularly in Mexico—offer concentrated infusions of mesenchymal stem cells (MSCs) sourced from umbilical cords, bone marrow, or adipose tissue, vigorous physical exercise itself mobilizes the body’s innate stem cell reserves. Comparing these two forms of stem cell “delivery”—one endogenous and one exogenous—reveals both the scale and potential of natural biology versus commercialized medical intervention.
