What are stem cells?
Stem cells are the primary cells of the human body. Every other cell is derived from a stem cell, including blood cells, nerve cells, etc. It acts as a ‘producer’ of new human cells and orchestrates the different cells that reside in the human body.
In the initial phase of the human lifecycle, fertilized egg divides into embryonic stem cells, and then continue to differentiate into various cells to form a complete human being. Besides, these stem cells also migrate to different parts of the body for tissue repair and regeneration such as during trauma or injury. However, the number of stem cells in the human body gradually decreases with age, which in turn causes aging.
