New Powerful Tool For Human Islet Purification • OptiPrep-UWS ? • IPITA 1999 Sydney • @1MEMO 20260325

Poster (#P298) Michel van der Burg, 7th World Congress of the International Pancreas & Islet Transplant Association, Sydney (Australia) August 22–25, 1999 . 1MEMO_20260325_1 TakeNode 770715b8-ca68-4c00-8a24-24fe0d216c10

Outcome of the first series of human islet purifications with the novel Iodixanol -UWS density gradient — developed originally in the difficult model of pig islet isolation in our Leiden Islet Laboratory of the LUMC (2) — and, performed in 1998 during my working visit at the “fast track” center of the Diabetes Research Institute (Scientific director Prof. C. Ricordi, MD) of the University of Miami , in Miami, Florida, USA .

Notes

Abstracts of previous IPITA meetings had been published in print in scientific journals , however, at the turn of the millennium in 1999, with the rise of the internet , the 7th IPITA congress abstracts were published online only at the official website of the IPITA, in Oxford at the time (www.jr2.ox.ac.uk/ipita), and cannot be retrieved now.
I kept an archive with photocopies of our abstracts published in print in the Abstract Book of the 7th IPITA. Here that abstract of poster presentation P298 at page 169 in the Programme and Abstract Book.

July 3, 2014 - Holland, Leiden University Hospital, 25 years ago : Photocopy June 13, 1989 surgery journal highlighting the moment of islet transplantion at our start of a first series of succesfull islets graft transplants in the Netherlands, using a simple yet very novel approach that eventually, recently, became a worldwide standard for transplanting clinical grade purified islets in insulin-dependent diabetic patients.
