Stem cells are the foundational cells of the human body, giving rise to all other cell types, such as blood cells, nerve cells, and more. They serve as the “originators” of new human cells and coordinate the various cell populations within the human body.
During the early stages of the human life cycle, a fertilised egg undergoes division, yielding embryonic stem cells, which subsequently specialise into various cell types to construct a fully developed human being. Furthermore, these versatile stem cells also migrate to different regions of the body to facilitate tissue repair and regeneration, particularly in response to trauma or injury. Nevertheless, as humans age, the quantity of stem cells in the body gradually diminishes, contributing to the ageing process.
