VUMC Islet and Pancreas Analysis (IPA) Core

Overview of Services

The Islet and Pancreas Analysis Core (IPA Core) is a core of the Vanderbilt Diabetes Research and Training Center (DRTC). Pancreatic islet biology, development, and function are major DRTC research areas with investigators studying a variety of islet-related processes ranging from intracellular signaling, immunology of type 1 diabetes, islet-enriched transcription factors, to islet transplantation. The objective of the core is to facilitate research of DRTC-affiliated investigators by providing high quality, well-characterized mouse pancreatic islets.
