Our History


Human Islet Genotyping Initiative (HIGI)

March, 2022

HIGI is directed by Dr. Anna Gloyn of the Translational Genomics of Diabetes Lab in the Department of Pediatrics at Stanford University School of medicine. The mission of the HIGI is to generate array-based genotype data on all islet donors to enable a summary of their genetic risk for diabetes to be displayed for users.


Stored Resources

November, 2021

The IIDP is pleased to announce the release Stored Resources. Using Stored Resources, you can search and request inventory of flash frozen islets and histology slides by race, sex, disease status, and age. This new feature also allows the user view received or requested islets, slides, frozen islets, acinar that are part of the stored resources.

Pancreatlas Integration with HIPP

June, 2021

The IIDP is pleased to announce the release of our new integration with PancreatlasTM platform. The goal of Pancreatlas is to organize and make accessible full-resolution images from a diverse array of human pancreas samples. Through this “bi-directional” integration, full-resolution images of certain islet preparations in the IIDP-HIPP system will be viewable in Pancreatlas. Users will be able to directly link out to view islet image in the Pancreatlas from the Histological Analysis section of the IIDP-HIPP system. Additionally, the entire IIDP-HIPP image collection will be available in the Pancreatlas, and the user will be able to link directly into the IIDP-HIPP system to view additional islet phenotyping data for a given islet preparation.

Phenotyping Data Integration with HPAP PANC-DB

June, 2021
Integration between HPAP PANC-DB and IIDP to provide human islet phenotyping data on HPAP Donors.
  • New IIDP webpage to display Human Islet Phenotyping for HPAP donors
  • Link to Pancreatlas
  • Link to HPAP PANC-DB donor webpage
  • Link on PANC-DB website to IIDP Human Islet Phenotyping for HPAP donors

Research Data Repository (RDR)

May, 2021

The Research Data Repository (RDR) is available to any researcher that is interested in obtaining data related to IIDP human islet isolations. Investigators interested in accessing the RDR would fill out a short data study application that will be reviewed by NIH and IIDP. Upon approval of the application, you will have access to the data on 1,400+ IIDP human islet isolations with over 200 data fields.

The RDR provides a convenient way for investigators to search for data on human islet isolations including:
  • Detailed donor data
  • Islet broadcast data
  • Islet phenotyping data (purity, viability and hormone secretion profiles)
  • User-invoked filters
  • Options to save custom filter profiles and record lists

IIDP Subscription Summary Released

October, 2020

IIDP Subscription Summary Released: October 1, 2020 IIDP Researchers now have access to subscription data including payment and invoice histories. Researchers can now process secure transactions via credit card directly on the IIDP secure website.


Alberta Diabetes Institute

August, 2019

The IIDP launched a project with the Alberta Diabetes Institute (ADI) Islet Core at the University of Alberta, Edmonton, to provide phenotyping data on the human islets that are received by researchers through their distribution program.

Non-Islet Pancreatic Tissue Distribution

May, 2019

IIDP starts the distribution of the Non-Islet Pancreatic Tissue (NIPT) that remains after the isolation and purification process. Commonly known as “acinar” tissue. The offers for NIPT will be made prior to the islet broadcasts and will not be contingent or otherwise linked to the islets from the same donor. The NIPT will be available as both freshly isolated and flash frozen samples, in most cases.

Islet Data Checklist for Publication

January, 2019

IIDP Aids Research Rigor through Automated Islet Data Checklist: In response to the recent Review (Hart &Powers) and Editorial (Poitout et al) published in Diabetologia (online in December and in the February print issue 62) the IIDP has made available to approved investigators an automated means to populate the newly required Checklist of islet characteristics for human islet experiments for manuscript submissions to the journals Diabetologia and Diabetes.


HIPP Data Released to IIDP Investigators

December, 2018

IIDP Investigators who have received islets from IIDP are now able to access and retrieve extensive phenotypic data on their islet preparations.

Expanded Donor Data Download

August, 2018

IIDP Researchers can now download expanded donor data from the United Network for Organ Sharing (UNOS) for received shipments.

RRID Generation

May, 2018

IIDP adds an automated tag called a Research Resource Identifier (RRID) to all isolations. This identifier is generated in collaboration with the National Center for Biotechnology Information (NCBI) and dkNET, through which RRID metadata is catalogued and tracked. IIDP has generated this identifier for every one of their islet preparations, in order to cooperate with the National Institute of Health (NIH) mandates for Rigor and Reproducibility.

IIDP Islet Award Initiative

January, 2018

Islet Award Initiative: January 18, 2018 New and established investigators with novel research concepts can apply for 100,000 free IEQs for proof of principle experiments. This new program is being supported by generous contributions from JDRF. Applications are accepted each quarter online at https://iidp.coh.org/onlineapp

Fall, 2017

Current IIDP Grant Selection of Five Isolation Centers

Fall, 2017

In the Fall of 2017, with the renewal of its NIH-funded grant, the IIDP selected 5 islet isolation centers to provide high quality human islets to the diabetes research community. These centers are strategically located across the United States. The 5 centers continue to provide excellent islet production and pre-shipment data to the diabetes research community worldwide.

July, 2016

First HIPP Shipments

July, 2016

Since July of 2016, the Human Islet Phenotyping Program has been obtaining post-shipment data on islet shipments to investigators. This provides additional information regarding the integrity of the islets post-shipment and provides purity, viability and functional data that will be available to investigators through the IIDP website.

October, 2012

Current IIDP Grant Selection of Six Isolation Centers

October, 2012

In 2009, the IIDP issued RFAs for islet isolation centers to serve as IIDP Centers providing high quality human islets to the diabetes research community. After careful review of islet isolation center production and capabilities as well as geographic location, the IIDP selected 6 centers to participate in the program. In 2012, the grant was renewed and the same 6 centers have remained as the current islet isolation centers affiliated with the IIDP.

January, 2011

Pilot Program Initiated

January, 2011

In an effort to support investigators new to human islet research, investigators with bridge funding, and investigators wishing to pursue small pilots prior to submitting a grant, the IIDP initiated a Pilot Program to provide investigators with up to 250,000 IEQs without the need to pay a subscription fee. Multiple investigators have used this option to date and over 85% have succeeded in acquiring funding post Pilot Program.

April, 2010

First CIT Islet Broadcast

April, 2010

The Clinical Islet Transplant (CIT) Program supported by NIDDK in 2010 requested that islets isolated but not used for transplant from the CIT program be offered to the research community so that this precious resource was not wasted. IIDP added all active CIT centers as islet isolation centers and distributed islets from the CIT.

August, 2009

Conversion of ICR to IIDP

August, 2009

In 2009, City of Hope, under the guidance of Dr. Joyce Niland, won an NIH RFA award for a contract to supply human islets to the research community. City of Hope won the award based on the management of the previous Islet Cell Resource (ICR) 2001 grant supported by National Center for Research Resources (NCRR). The IIDP has been serving the needs of the islet research community since 2004 with the distribution of high quality human islets.

April, 2008

Start of JDRF Islet Distribution Program

April, 2008

In 2008, the JDRF suggested that their islet isolation Centers distribute islets to JDRF investigators through the existing ICR web-based infrastructure utilizing the MAID algorithm. The ICR incorporated these Centers into its distribution program. Any islets not distributed to JDRF investigators were subsequently distributed to ICR investigators. This served as a way to maximize the use of isolated human islets for research and grew the ICR’s investigator base.

March, 2007

1st Islet Broadcast via Matching Algorithm for Islet Distribution(MAID)

March, 2007

In order to ensure that all approved investigators were treated fairly in the distribution of human islets by the ICR, the ICR-ABCC developed an algorithm that matches the investigators’ requests for islets and donor criteria with the islets available for distribution. This algorithm ensures a fair and equitable distribution of human islets to the research community based on investigator need.

February, 2004

Start of ICR Basic Science Distributions

February, 2004

In 2004, the ICR who had previously distributed human islets for clinical transplant, began distributing human islets for research. This distribution occurred by a manual method of calling investigators to determine if the islets available could be placed. From 2004 to 2007, the ICR worked on developing an automated system for islet distribution and in 2007 succeeded in distributing islets using the MAID algorithm.

September, 2002

Administrative and Bioinformatics Coordinating Center

September, 2002

Shortly after the creation of the ICR, the National Center for Research Resources (NCRR) commissioned the Administrative and Bioinformatics Coordinating Center (ABCC) for the administration and data support of the ICR. City of Hope, under the leadership of Dr. Joyce Niland, was granted this award and maintained the administrative and biostatistical management role of the ICR until the program's completion and transition into its new iteration as the Integrated Islet Distribution Program (IIDP) in 2009. As the ICR-ABCC, City of Hope provided web development, data collection, statistical analysis, scientific study facilitation, and islet distribution infrastructure and logistical support.


Islet Cell Resource Project Launched


The Islet Cell Resource Centers (ICRs), were funded by the National Center for Research Resources and the National Institute of Diabetes and Digestive and Kidney Diseases, components of the National Institutes of Health, Department of Health and Human Services from September, 2001 through July, 2009, and comprised an interactive group of 10 academic laboratories charged with three major goals: 1) to provide pancreatic islets of cGMP-quality to eligible investigators for use in FDA-approved, IRB-approved transplantation protocols; 2) to optimize the harvest, purification, function, storage, and shipment of islets while developing tests that characterized the quality and predicted the effectiveness of islets transplanted into patients with diabetes mellitus; and 3) to provide pancreatic islets for basic science studies.
