Stem Cell Isolation and Xenotransplantation Core This core has continued to provide high-end cell sorting and transplantation services to a large and still growing group of investigators. These services include cell isolation from primary human tissue (through high-speed multi-parameter cell sorting) as well as diverse transplantation techniques into various mouse or rat xenografting models. The facility also offers new services for cancer stem cell transplantation and in vivo stem cell sampling.
