Stem cells develop best in 3D
Copenhagen, Denmark (SPX) Nov 22, 2012
Scientists from The Danish Stem Cell Center (DanStem) at the University of Copenhagen are contributing important knowledge about how stem cells develop best into insulin-producing cells. In the long term this new knowledge can improve diabetes treatment with cell therapy. The results have just been published in the scientific journal Cell Reports. Stem cells are responsible for tissue growth and tissue repair after injury. Therefore, the discovery that these vital cells grow better in a three-dime ... read more
