At the DRI and Foundation, our mission is to discover a biological cure for diabetes – to restore natural insulin production and normalize blood sugar levels without imposing other risks. DRI scientists have been making steady progress toward this goal and, in early March, unveiled the DRI BioHub, a bioengineered “mini organ” that mimics the native pancreas, containing thousands of insulin-producing cells that can sense blood sugar and release the precise amount of insulin needed - in real time.

The BioHub is a platform that addresses destroyed by the immune system in those these challenges by drawing on recent with type 1 diabetes.

“The progress in islet transplantation has been incremental and has allowed us to get to this important juncture. The DRI BioHub gives us a tool to combine all we’ve learned through the years of clinical testing and take the next leap forward. I am confident that this approach could move cellular therapies and biological replacement strategies for the cure of diabetes to our final goal,” says Camillo Ricordi, M.D., Stacy Joy Goodman professor of surgery and director of the Diabetes Research Institute (read "Under the Microscope with Dr. Ricordi" on page 10). Among the platforms being tested for a DRI BioHub is a porous, sponge-like material approximately the size of a quarter that is compatible with the human body. Islet cells are gently seeded on this protective platform, allowing cells to nestle within the individual pores. Continued on Page 5
Pearlman Steps Down
In Memoriam
DRI BioHub Gifts
Walk with Walgreens
After 20 years, DRIF President and CEO Robert A. Pearlman stepped down effective June 30.
The DRI family is deeply saddened by the passing of dear friends and longtime supporters Sylvia and Rowland Schaefer.
Several generous donors like Hon. Maryanne Trump Barry (with her grandson, Robert Desmond) have made significant gifts to support the DRI BioHub initiative.
Thousands walked and raised more than $400,000. On site were celebs like Nat Moore, Chris Conlin and Bobby Harden of the Miami Dolphins.
