A novel iodixanol density gradient for purification of pancreatic islets was developed in the difficult pig model. The pig islets restored normal blood sugar levels after xeno transplantation in diabetic mice.

I started an archive at Archive.org November 11, 2010 with this slideshow (pdf) of my January 1999 oral presentation in Igls (Innsbruck), Austria, at the 18th Workshop of the AIDSPIT (Artificial Insulin Delivery Systems, Pancreas and Islet Transplantation) Study Group. (Now known as AIDPIT).
The presented results of this innovative islet purification method — developed over nearly 10 years (from 1989) in our Leiden islet laboratory (LUMC) — were the outcome of work I had done spring 1998 with the human islet transplantation group of Camillo Ricordi at the Diabetes Research Institute in Miami , Florida, USA.

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….”

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.
