Sequential Transplantation of UCBSCs and Islet Cells in Children and Adolescents With Monogenic Immunodeficiency T1DM
Trial Parameters
Brief Summary
This study evaluates the efficacy of sequential transplantation of umbilical cord blood stem cells and islet cells in children with monogenic immunodeficiency type 1 diabetes mellitus. Umbilical cord blood stem cell transplantation will be performed first. Children with stable immune reconstruction will than receive islet cell transplantation.
