Evaluation of survival of grafted islets in diabetic rat liver. Livers with grafted islets were fixed and sections prepared for HE stain (a) (×100), immunohistochemical stains for human mitochondrial antigen (b) (×400), human C-peptide (c) (×400) and human glucagon (d) (×400) respectively. In addition, serum level of human C-peptide increased in progenitor cell group (e)
