Physiological mechanism of adult autologous stem cells
It is not yet absolutely clear how bone marrow stem cells participate in healing processes. For a long time, it was assumed that stem cells simply replace the damaged cells. This seems to be the case to some extent, but in recent years, research has shown that stem cells more often stimulate the healing of the damaged tissue rather than replacing it completely. The adult stem cells discharge messengers that stimulate both damaged and healthy cells, thus strengthening the whole tissue – for example a myocardial muscle.
Scientists assume that the redundant messengers give a starting signal for endogenous regeneration. These cells start processes with an anti-inflammatory and circulation-enhancing action, for example stimulating the growth of new arteries.
