Background: In this study, we carried out bone marrow and foetal liver cell transplantation to determine if these cells could differentiate into pancreatic β-cells or promote regeneration. Methods: To exclude an artificial or immunological influence for induction of diabetes to recipients, Akita mice, which develop diabetes spontaneously, were used. In addition, we used mice harbouring the transgenic green fluorescent protein (GFP) reporter for insulin 1 gene as donors to mark donor-derived β-cells. Results: All transplanted Akita mice after intravenous injection showed full donor chimerism in peripheral blood analysis. Their diabetic state represented by blood glucose levels did not change after transplantation. In spite of examination of more than 200 islets in each group, we could not find GFP-positive cells in any of the recipients. Conclusions: Bone marrow cells or foetal liver cells do not differentiate to new pancreatic β-cells or promote regeneration in Akita mice, a non-chemical or non-immune model of diabetes.
