Islet Transplantation LUMC News Surprise • @1MEMO 20251020

Diabetic (dutch ‘Suikerzieke) … Parool, 6 Jan 1990 • @1MEMO 20251020

Big surprise today , to encounter this nice news article by journalist Rob van Dijk reporting on our pancreatic islet transplantation breakthrough in the Leiden University Hospital (now LUMC) in the Amsterdam based Dutch national newspaper Parool , Saturday 6 January 1990 (1).

I was searching actually for a better copy of a different news article I have archived on my clinical islet transplantation work (Newspaper Volkskrant 10 April 1999) in the Delpher archive of the National Library of the Netherlands , scrolling the search results, and noticed this Parool article – I didn’t know it existed 😉

Journalist Rob van Dijk did not interview me for the Parool, so I assume his source was the interview I gave for publication in Cicero, the biweekly LUMC publication, and the Dutch newspaper ‘Leidsch Dagblad’, and posted a year ago (2).

The articles reports (my translation from dutch*) :

Transplantation

Islet transplantation has been possible for a few years now, but it doesn’t (yet?) work in humans. The technique itself isn’t that complicated: as many islets of Langerhans as possible are extracted from a pancreas, injected into the diabetic patient’s liver or spleen, and thus, start producing insulin. However, that “thus” is still a bit tricky… …
The major problems lie in the fact that the yield of properly functioning islets is too small (at least 30 percent of the islets must be obtained undamaged to achieve sufficient insulin production after a transplant) and that the suspensions are too impure. Nevertheless, progress is being made.
The best news comes from Leiden University Hospital. There, biologist M. van der Burg, MSc has developed a method to isolate a very high and pure yield of islets from a dog’s pancreas. Van der Burg succeeded in isolating 40 percent of the vital islets from a dog’s pancreas. Through special processing, he was able to completely purify these cell clumps of 90 percent of excess and complicating pancreatic tissue. These islets were injected into the spleen of the same dog, where they produced sufficient insulin. This initial experiment has since been repeated in Leiden with several dogs with the same success. However, major challenges remain, not the least of which is the rejection problem. The Leiden experiments used the dog’s own tissue. The big question remains how the human immune system reacts when islets from a donor are injected.

*NL (dutch) quote :

Transplantatie

Sinds een paar jaar is eilandjestransplantatie wel mogelijk, alleen, bij de mens werkt het (nog?) niet. De techniek is op zichzelf niet zo ingewikkeld: men haalt zoveel mogelijk eilandjes van Langerhans uit een pancreas, spuit die bij de suikerzieke in lever of milt in en dan gaan ze dus insuline maken. Met dat ‘dus’ ligt het echter nog moeilijk… …
De grote problemen schuilen hem erin dat de oogst aan goed werkende eilandjes te gering is (men moet ten minste 30 procent van de eilandjes onbeschadigd te pakken krijgen om na een transplantatie voldoende insulineproduktie te verkrijgen) en dat de suspensies te onzuiver zijn. Toch zit er schot in.
Het beste nieuws komt uit het academisch ziekenhuis te Leiden. Daar heeft de bioloog drs. M. van der Burg een methode ontwikkeld om uit een hondepancreas een zeer hoge en zuivere oogst aan eilandjes te isoleren. Van der Burg slaagde erin uit de alvleesklier van een hond 40 procent van de vitale eilandjes te isoleren, door een speciale bewerking kon hij deze celklompjes voor 90 procent absoluut zuiveren van overbodig en complicerend pancreasweefsel. Deze eilandjes werden ingespoten in de milt van dezelfde hond en produceren daar voldoende insuline. Dit eerste experiment is in Leiden intussen met meerdere honden met hetzelfde succes herhaald. Maar er zijn nog grote problemen op te lossen en bepaald niet het geringste daarvan is dat van de afstoting. Bij de Leidse experimenten werd gebruik gemaakt van eigen weefsel van de hond. De grote vraag blijft hoe het immuunsysteem van de mens reageert als er eilandjes van een donor worden ingespoten.

SURVIVOR

Installation stolperstein Sally Frankenthal, 11-13 Rue Marie-Thérèse, Brussels, 11 April 2025.
Belgian Resistance fighter Nelly Quintart has been hiding the Jewish Frankenthal family — Esther, Adolphe, and daughter Sally Frankenthal — at her place, 13 Rue Marie-Thérèse in Brussels, from September 1942 until the liberation in 1944.
Sally Frankenthal recommended to Yad Vashem in the late 1990s the ‘Righteous Among the Nations’ medal for ‘Nelly Quintard’, which Nelly received posthumously. The surname ‘Quintart’ was misspelled as ‘Quintard’ in Sally’s correspondence with Yad Vashem.

Together, the families of Sally Frankenthal and Nelly Quintart and researcher, filmmaker Michel van der Burg took the initiative June 2023 for this Stolperstein, a tribute to Sally Frankelthal, to recall passers-by to this story of Sally & Nelly, in front of the place where the house where Nelly Quintart hid the Frankenthal family used to stand – now a large new building at 11-13 Rue Marie-Thérèse in Brussels.

April 11, 2025 this beautiful and moving Stolperstein ceremony took place with music by André Reinitz on accordion, thanks to the Association pour la Mémoire de la Shoah joining our initiative July 2023 and making it happen, especially Marcel Zalc (president) and Bella Swiatlowski, coordinator Stolpersteine. Thank you municipal workers for placing this stolperstein. Film by Michel van der Burg | Miracles•Media.

The story of Sally & Nelly is now integrated into the largest decentralized memorial in the world, thanks to the artist Gunter Demnig and his team…hand-stamping each letter into the brass of this stone.

Renée Cassin , goddaughter of Nelly Quintart , shows Michel van der Burg the miniature diorama she made in a glass showcase, with scenes of Belgian Resistance fighter Nelly Quintart hiding the Jewish Frankenthal family (Esther, Adolphe, and daughter Sally) at her place, 13 Rue Marie-Thérèse in Brussels, from September 1942 until the liberation in 1944, and a scene with the ‘Righteous Among the Nations’ medal for Nelly — recommended by Sally Frankenthal to Yad Vashem in the 1990s.
The film also features the original briefcase used by Nelly to secretly buy the daily food for all from multiple grocery stores.

Recorded April 11, 2025, in Guesthouse Marie-Thérèse – across the street of that historical site — on our way to the installation ceremony of the Sally Frankenthal Stolperstein, a stumbling stone to recall passers-by to the story of Sally & Nelly.
