Lucky #1 Islet • 20240811

Shortly after starting our Islet Lab end 1986, I hand-picked and photographed this special big heart-shaped isolated islet of Langerhans with Uncle Scrooge McDuck’s ‘lucky #1 dime’ in mind.
(dutch : Dagobert Duck’s geluksdubbeltje). This ‘First Islet’ poster was pinned to the wall in my study in the (small) Islet Lab ‘wing’ in the Cell Biology building of the Leiden University Hospital.

It’s an Islet of Langerhans isolated from a rat pancreas. For pilot work, the first months while developing our islet project plan, islets were isolated from rat pancreases.
I had started developing our basic lab methods… like eg. measuring the insulin secretion capacity and insulin content of isolated islets. A custom-made glass pipet was used to hand-pick and transfer the islets to little polypropyleen ‘Eppendorf’ tubes for insulin secretion tests with glucose stimulation.

Minneapolis 1989 Poster | 20240804

September 1989 at a symposium of two international societies in Minneapolis, USA (1) , I presented this first poster on the ‘ invention ‘ of using the UW solution ( the University of Wisconsin organ preservation solution) during pancreatic islet isolation, with the exciting discovery of near-complete purification of islets of Langerhans in the laboratory for transplantation in diabetic patients.

Here the remastered 20240804 edition of that Minneapolis 1989 poster presentation.

The UWS data had been added ad hoc in the poster – that is , it wasn’t part of the accepted abstract. The first proceedings paper on our UWS work was also submitted at this meeting , and was published April ’90 (3).

A previous edition of the remastered poster was published here two years ago (2) but that edition had a different photo print (higher magnification, and without the bar indicator) of the purified islet preparation inserted, not the original image. This has been corrected now. In addition the original line spacing is now restored.

Leiden Islet Laboratory History • 20240803

Summer 1985… start of our Leiden Islet Transplant Laboratory by Paul van Suylichem (right) and Michel van der Burg (middle), both from the Surgery department — wondering how to start here our islet lab in this space – a former weighing chamber (left : stable weighing table) made available by the Cell Biology department of the Leiden University, headed by Prof J.P. Scherft. Where to put our equipment… the laminar flow cabinet, large centrifuge, fridge, freezer, shaking waterbath, microscopes, and a lot of disposables coming ?

I had started working in 1981 for the Pancreas project. Pancreas transplantation research with the surgeon Hein Gooszen , working on his PhD (1), and surgeon Reinout van Schilfgaarde – who headed the project – and in 1985 also started this islet project.

Summer 1986, when Reinout van Schilfgaarde together with Paul van Suylichem moved to the Groningen University Hospital (2), Hein Gooszen and I decided to make a fresh start with the now operational Leiden Islet Lab…

Fifteen years of research later we were ready to roll with the isolation of human islets of Langerhans, in our new GMP facility in the Leiden Univerity Medical Center (LUMC). September 2001, the National Health Care Institute positively assessed our permit application for Transplantation of Islets of Langerhans in the LUMC (3,6), followed by approval May 2003 of the islet bank by the Health and Youth Care Inspectorate of the Ministry of Health, Welfare and Sport (VWS).

Note : The Dutch dissertation system has a tradition of accompanying the generally very specialised PhD thesis with ten or more propositions (other ‘theses’), that should be ‘defensible’, and while at least some should be related to the dissertation, others generally reflect the PhD candidate’s broader interests, and the last one is often playful.

Publisher’s description

Pancreatic islet transplantation by a new method is introduced here : the isolation of islets in an organ preservation solution, the University of Wisconsin solution. A new concept allowing for the first time large-scale isolation and transplantation of consistently near 100% pure islets of Langerhans in a preclinical dog model with fasting normoglycemia up to 3 years posttransplant. Detailed metabolic studies demonstrated normal insulin levels after meals with preservation of gut hormone action stimulating insulin secretion at the mild hyperglycemia after meals. The introduction of the University of Wisconsin solution organ preservation solution for islet isolation at the start of these studies in 1989 is a new concept … and has been shown by now in 2022 , world-wide , to make the future of islet isolation and transplantation methods for insulin-dependent diabetes mellitus (IDDM).

(Captions at last page of the dissertation)

1. Paul Langerhans
2. Section of the normal dog pancreas showing islets stained reddish-brown (immunostained for insulin)
3. The author, watching the dog islet isolation procedure in the Minneapolis surgical research laboratory
4. Start of the operation in the dog (From left to right: Professor Hein G. Gooszen, Ms. M. Jane Field (Minneapolis), and Dr. Onno R. Guicherit, at our surgical laboratory)
5. The pancreas is removed
6. Infusion of the collagenase solution via the ducts in the dog pancreas – collagenase leaking from the pancreas is recirculated using a pump (Islet laboratory, at the Department of Cell Biology and Histology, Leiden)
7. During collagenase digestion at 37-39°C the pancreas falls apart (non-stained pancreatic exocrine tissue and free-ed small blood vessel, at low magnification)
8. Dissociated pancreatic tissue
9. Tissue is further dispersed by aspiration in a syringe, and sieved to remove undigested fragments, ducts and vessels ~ demonstrated by Ms. Jane Field at our islet laboratory.
10. Tissue suspension demonstrating low purity of the islets (stained red by dithizone) obtained by dextran gradient separation after isolation in the RPMI tissue culture solution (dark-brown exocrine fragments remain unstained)
11. Pure islet suspension (after dithizone staining) obtained by density separation in Percoll gradients (in University of Wisconsin solution) after islet isolation in the University of Wisconsin solution (islets are only slightly stained due to poor diffusion over the cell membrane in the preservation solution)
12. Section of highly purified islets obtained by dextran density separation after isolation in the University of Wisconsin solution
13. Islets are autotransplanted by infusion in the spleen of the dog
14. Transplanted islet in section of the spleen of one of the dogs shortly after the onset of fasting hyperglycemia at three months posttransplant (immunostained for insulin)
15. Highly purified human islets obtained by Percoll density separation after isolation in the University of Wisconsin solution (immunostained with gold for insulin; not counterstained)
