1. A method of producing pancreatic beta cells in a subject, comprisingadministering to the subject a vector comprising a glucagon promoter operably linked to a nucleic acid sequence encoding heterologous Pancreas duodenal homeobox protein (Pdx) 1 and a nucleic acid sequence encoding Musculoaponeurotic fibrosarcoma oncogene homolog A (MafA), wherein the vector does not encode Neurogenin 3 (Ngn3), wherein the subject is not administered any other nucleic acid encoding Ngn3, wherein the glucagon promoter a) consists of the nucleic acid sequence of SEQ ID NO:

  • 1, or b) comprises the nucleic acid sequence of SEQ ID NO;

    3, and wherein the vector is administered intraductally into a pancreatic duct of the subject,thereby inducing alpha cells to transform into pancreatic beta cells in the subject.
