  • Ingap protein involved in pancreatic islet neogenesis
    Patent number: 5840531
    Abstract: Cellophane wrapping (CW) of hamster pancreas induces proliferation of duct epithelial cells followed by endocrine cell differentiation and islet neogenesis. Using the mRNA differential display technique a cDNA clone expressed in cellophane wrapped but not in control pancreata was identified. Using this cDNA as a probe, a cDNA library was screened and a gene not previously described was identified and named INGAP.
    Type: Grant
    Filed: September 9, 1996
    Date of Patent: November 24, 1998
    Assignees: MoGill University, Eastern Virginia Medical School of the Medicine College of Hampton Roads
    Inventors: Aaron I. Vinik, Gary L. Pittenger, Ronit Rafaeloff, Lawrence Rosenberg, William P. Duguid
