“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 .
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 ( UWS ) — 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.
