“Breakthrough in research into treatment of diabetics. Discovery by doctors of Leiden University Hospital” …headlines the Dutch newspaper ‘Leidsch Dagblad’ (1).

The dutch newspaper ‘Leidsch Dagblad’ reports October 24, 1989, on a breakthrough in the treatment of diabetic patients…successful transplantation of the insulin producing ‘islets’ in dogs, after isolation of the islets ​​using the UW organ storage solution (UWS)

The first successful transplant June 13, 1989 was a big step. Generally multiple pancreases are needed for an adequate number of purified islets for one transplant. Here the dog’s pancreas was used for the isolation of islets, that were injected back in the animals’ spleen.

‘The breakthrough in the research came when Van der Burg came up with the idea of ​​using the UW organ storage solution — developed several years ago at the University of Wisconsin — for the preservation of the islets. This turned out to yield good results. The yield of pure islets could be increased using this method.’

One more thing

We reported long-term function of the islet transplants (3,4). Failure after 3.5 years of a well-functioning islet transplant is puzzling. Nowadays, in clinical islet transplantation, failure of long-term functioning grafts in diabetic patients is still puzzling. Therefore, note (data not published before), that body weight of this autografted animal had increased to almost 150%, from 12.5 kg at the time of islet transplantation, to 18.0 kg at the time of graft failure 3.5 years later (Dec. 1992) — obviously, with an increased insulin demand that may have contributed to graft failure.

Out Of Service | 20140911

Out Of Service | 20140911 | 1-memo•com | In the morning of 9/11 2001 logistics forced me to officially announce a temporarily – 1 week – ‘out of service’ of our Leiden islet isolation and transplant center. Our center was started earlier that summer of 2001 at the Leiden University Medical Center. So, I decided to have a short vacation abroad – heaven, after being on call 24/7 almost non stop for years. Later that day at home, I was downstairs watching TV — because upstairs near my workroom the central heating was being replaced – when I saw the CNN breaking news about the plane crashing into the World Trade Center. That day would become a landmark in history and the course of my life.

Background image : Microscopy picture I took of purified human Islets of Langerhans – tiny clumps (size around 1/10 mm or 1/25 inch) of 10s to 1000s of cells that produce hormones like insulin – these cells are just visible when you enlarge this 50x microscopy picture : as tiny translucent ‘balls’ or ‘spheres’. The red color is from a stain that binds to the insulin cells.
