A low frequency of pancreatic islet insulin-expressing cells derived from cord blood stem cell allografts in humans

We report that umbilical cord blood cells do have the capacity to migrate to the pancreatic islet and differentiate into insulin-expressing cells in humans. This is in contrast to the absence of insulin-expressing cells with an opposite-sex complement of sex chromosomes present in human pancreas after prior bone marrow transplant, when the same methods were used as here.
