The poster was originally designed and produced on a Macintosh computer and Imagewriter dotmatrix printer, June 3, 1991, using the MacDraw II application, with graphs from Cricket Graph. That 1991 Mac file was remastered today in LibreOffice Vanilla.

Printing journal on ‘F4UW’ (in porcine islet isolation) …Apple Powerbook 160 , Islet Laboratory, Leiden University Hospital 1990s. Found a snippet correspondence on F4UW :
“Dear Bjørn…I checked my journals re the use of ficoll. I have temporarily used Ficoll-400DL from Sigma in 1996 for making Optiprep-UWS gradients and UWS as the isolation solution. The reason was that I had no more Pentastarch
left from a shipment received from DuPont…Most of the experiments used WOP prepared from 1:1 optiprep and either F4UWS or 8 percent Ficoll in UWS….”
“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.

Poster creation
The poster was designed and produced May 1992 on a Macintosh computer using MacDraw II (with bar graphs from Cricket Graph) and printed landscape across a chain of several sheets of paper using the Imagewriter dotmatrix printer.
For this 2024 remastered poster below, the 1992 MacDraw II file was converted and edited using LibreOffice Vanilla, and next Pixelmator Pro was used for additional ‘repair’ (conversion issues with the many layers used for ‘tubes’ creation) and the insertion of the photo scans.

Lyon 1991 Percoll Poster | 20240731 • 20240808
20240808 – remastered poster : Following the first publication here last month (20240731) of the original 1991 MacDraw poster opened (converted) in LibreOffice Vanilla (1), I learned how to do some editing in the LibreOffice app to further restore poster layout details such as line spacing, and font style. An archive photo of another poster presentation in Pittsburgh in 1992 (that will be posted here soon) guided this restoration.
Current workflow : 1) opening the MacDraw II file in LibreOffice Vanilla 2) editing in in LibreOffice Vanilla , saving as LibreOffice Vanilla file (OpenDocument Drawing – extension odg). 3) opening the photo tiff image in the Mac’s Preview app, and copying the displayed image to the clipboard 4) pasting the clipboard image in the LibreOffice doc , and dragging to adjust size and location 5) exporting the file as PDF (image resolution 300 DPI ; PDF/A-1b ; PDF/UA). 6) Converting the PDF in the Preview app to TIFF 144 pixels/inch. 7) Adding caption , metadata etc with JPEG conversion in PhotoMill.
The 20240731 post now has this updated 20240808 – poster image.

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.

Following first introduction of the use UWS (the UW organ preservation solution) for pancreatic islet isolation in 1989 , next also purification of the islets in UWS was presented in 1991, with two options.
One option was an iso-osmotic density gradient solution of Percoll in UWS. The second option was a density gradient solution created by increasing the Pentastarch concentration in UWS (7) . Note that Pentastarch is a component of UWS.
The Percoll-UWS poster was posted recently (8)
Here the remastered poster presentation on Pentastarch-UWS :
Pentastarch in UW (SUW): a new method for complete islet purification. 3rd International Congress on Pancreatic and Islet Transplantation, Symposium on Artificial Insulin Delivery System, Lyon (France) June 6–8, 1991.
The poster was designed and produced on my personal Macintosh computer and Imagewriter dotmatrix printer, the night of June 3-4, 1991, using the MacDraw II application.
The Apple Imagewriter-II matrix printer, allows printing landscape across a chain of several sheets of paper, strips, the width of the poster (here 3 sheets long). The strips of the poster (here 3 strips) were then glued on site along the perforation, creating the 36/24 inch poster.
Finally the photo print of the purified islets was pasted in the poster at the spot at the venue in Lyon. In Lyon a photo of a dithizone stained Pentastarch purified islet sample was shown. To save time the archive was not searched for that image, and another image of Pentastarch purified islets was inserted in this remastered edition, a reflection contrast micrograph of an ultrathin section of Pentastarch purified islets immuno-stained with gold on insulin in the islet cells.
Nowadays, it is a challenge opening such old Mac files … Luckily, I was able to open this MacDraw II poster file in LibreOffice Vanilla and now learned to use the app to further correct most conversion issues. Pixelmator Pro was used for additional ‘repair’ and insertion of the photo scan.
