How do my cells work?
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 also more often stimulate the healing of the damaged tissue rather than replacing it completely. The adult stem cells discharge messengers (interleukines, neurotrophic factors, growth factors) that stimulate both damaged and healthy cells, thus strengthening the whole tissue – like for example myocardial muscle tissue.
Scientists postulate that the redundant messengers give a starting signal for endogenous regeneration. These cells start processes with an anti-inflammatory and circulation-enhancing action, such as stimulating the growth of new arteries and smaller blood vessels.
Small cells…doing big things…
