Stem cells
are cells that renew themselves and that can develop into one or several types of differentiated cells. They replicate on their own, divide themselves asymmetrically and have a high proliferation and differentiation potential 71. Besides embryonal stem cells, induced pluripotent stem cells and mesenchymal stem cells (mainly from adipose tissue, bone marrow and umbilical cord) are worked with 18. They are, among others, used for the development and production of cell therapeutics.
