If an organ does not function optimally or is damaged in some way and needs cell-replacement, the bone marrow receives a signal and, recognizing the information, releases the stem cells. Stem cells travel through the bloodstream to the signal-sending area using a special messenger.
When they arrive at the target area, they must enter the organ. They then begin to divide, creating 1,000 to 6,000 copies per cell, and then become the appropriate cells of the tissue. In the blood, we can count an average of 2.4 stem cells per microliter, which means 12 million stem cells per 5 litres of blood, but after the age of 25-30, this number gradually decreases. However, the declining number of stem cells can no longer result in adequate regeneration, due to which, along with ageing, the function of the organs deteriorates.
Bone marrow and tissue stem cells thus form the body’s natural regeneration system. It can be detected that the more stem cells in the body, regardless of age, the better the status of health will become.
