Stem cells – a gift of nature. Every time cells within our body age or die, they have to be replaced. Hematopoietic cells e.g. have a very short lifetime and are renewed on a daily basis. Acute situations such as accidents involving injuries of tissues (e.g. cuts, punctures) on the other hand call for immediate and fast tissue renewal.
For all these cases, nature has implemented a repair instrument: the stem cells. There are several sources of stem cells within our body that differ in accessibility and yield.
