This study, «Engineered epidermal
progenitor cells can correct diet - induced obesity and diabetes,» is the first to show that an engineered skin
graft can survive long term in wild - type mice with intact immune systems.
For the other adult patients that might still benefit from a cord blood donor, either two cord blood units are combined for a single transplant, or more recently, there are some exciting new
graft engineering technologies that are emerging to expand stem or
progenitor cells in the laboratory before infusion or modify the
cells in some way to make them more potent at the time of transplant.
