A Zebrafish Model of Diabetes Mellitus and Metabolic Memory

1Dr. William M. Scholl College of Podiatric Medicine, Rosalind Franklin University of Medicine and Science, 2Chicago Medical School, Rosalind Franklin University of Medicine and Science


JoVE 50232

Metabolic memory is the phenomenon by which diabetic complications persist and progress unimpeded even after euglycemia is achieved pharmaceutically. Here we describe a diabetes mellitus zebrafish model which is unique in that it allows for the examination of the mitotically transmissible epigenetic components of metabolic memory in vivo.

A Method for Mouse Pancreatic Islet Isolation and Intracellular cAMP Determination

1Department of Nutrional Sciences, University of Wisconsin-Madison, 2Department of Medicine, Division of Endocrinology, Diabetes, and Metabolism, University of Wisconsin-Madison, 3School of Pharmacy, University of Waterloo


JoVE 50374

Assaying in vitro β-cell function using isolated mouse islets of Langerhans is an important component in the study of diabetes pathophysiology and therapeutics. While many downstream applications are available, this protocol specifically describes the measurement of intracellular cyclic adenosine monophosphate (cAMP) as an essential parameter determining β-cell function.

Isolation of Human Islets from Partially Pancreatectomized Patients

1Department of GI-, Thorax- and Vascular Surgery, University Hospital Carl Gustav Carus, University of Technology Dresden, 2Molecular Diabetology, Paul Langerhans Institute Dresden, 3Department of Pathology, University Hospital Carl Gustav Carus, University of Technology Dresden


JoVE 2962

The supply of type 2 diabetic islets for research is insufficient. Here we share our protocol for isolating islets from patients undergoing partial pancreatectomy. This approach represents a unique venue for obtaining islets from type 2 diabetic and clinically matched non-diabetic subjects in adequate numbers for basic and clinical studies.

Accelerated Type 1 Diabetes Induction in Mice by Adoptive Transfer of Diabetogenic CD4+ T Cells

1Department of Microbiology & Immunology, Pennsylvania State University College of Medicine


JoVE 50389

We provide a reproducible method to induce type 1 diabetes (T1D) in mice within two weeks by the adoptive transfer of islet antigen-specific, primary CD4+ T cells.

A High-throughput Method for Measurement of Glomerular Filtration Rate in Conscious Mice

1Division of Nephrology-Hypertension, Department of Medicine, University of California, San Diego, 2San Diego VA Healthcare System


JoVE 50330

Measurement of glomerular filtration rate (GFR) is the gold standard for kidney function assessment. Here we describe a high-throughput method which allows the determination of GFR in conscious mice by using a single bolus injection, determination of fluorescein isothiocyanate (FITC)-inulin in plasma and calculation of GFR by a two-phase exponential decay model.

A Method for Murine Islet Isolation and Subcapsular Kidney Transplantation

1Molecular and Cellular Biochemistry, Center for Molecular Neurobiology, The Ohio State University, 2Integrated Biomedical Science Graduate Program, The Ohio State University, 3Comprehensive Cancer Center, The Ohio State University


JoVE 2096

Transplantation of isolated islets has been proposed to be a potential treatment for type 1 diabetes. Here we describe a method to isolate islets from mouse pancreata and transplant them to the subcapsular space of the kidney.

Improved Protocol For Laser Microdissection Of Human Pancreatic Islets From Surgical Specimens

JoVE 50231

Laser microdissection is a technique that allows the recovery of selected cells from minute amounts of parenchyma. Here we describe a protocol for acquiring human pancreatic islets from surgical specimens to be used for transcriptomic studies. Our protocol improves the intrinsic autofluorescence of human beta cells, thus facilitating their collection.

Near Infrared Optical Projection Tomography for Assessments of β-cell Mass Distribution in Diabetes Research

1Umeå Centre for Molecular Medicine, Umeå University, 2Cell Transplant Center, Diabetes Research Institute, University of Miami,, 3EMBL-CRG Systems Biology Program, Centre for Genomic Regulation, Catalan Institute of Research and Advanced Studies, 4Dept. of Computing Science, Umeå University


JoVE 50238

We describe the adaptation of optical projection tomography (OPT)1 to imaging in the near infrared spectrum, and the implementation of a number of computational tools. These protocols enable assessments of pancreatic β-cell mass (BCM) in larger specimens, increase the multichannel capacity of the technique and increase the quality of OPT data.

Assessing Replication and Beta Cell Function in Adenovirally-transduced Isolated Rodent Islets

1Department of Pediatrics, Indiana University School of Medicine, 2Department of Cellular & Integrative Physiology, Indiana University School of Medicine


JoVE 4080

This protocol allows one to identify factors that modulate functional beta cell mass to find potential therapeutic targets for the treatment of diabetes. The protocol consists of a streamlined method to assess islet replication and beta cell function in isolated rat islets following manipulation of gene expression with adenoviruses.
