The Fraunhofer Research Institution for Marine Biotechnology EMB has developed a patented process for harvesting human stem cells from sweat glands. This provides a new source of cells for use in regenerative medicine. Stem cells harvested from sweat glands have the distinct advantages of being easy to procure and raising no ethical concerns. Establishing a cell bank that stores autologous (the body’s own) stem cells opens up promising new treatment options. In addition, isolated human sweat glands are ideal organotypical, in-vitro test systems that can help the pharmaceutical and cosmetics industries to screen bioactive substances.
