Thanks Moreforme, The link from that article to the Diabecell was really interesting also,
Diabecell ,
In the earlier phase I trials, four people with type 1 diabetes who suffered from “hypoglycaemic unawareness” – in other words, they didn’t notice when their blood sugar levels became dangerously low – were implanted with a few of the cells. “In one patient, the implants reduced their daily insulin dose by 25 per cent, and hypoglycaemic unawareness disappeared,” says Elliott. The other three are being monitored, and Elliott says “results look very satisfying”.
Research is further ahead in Russia, where LCT began trials of Diabecell in 2007. Five patients have since been given higher doses and are successfully responding. Would be nice to know how those Russian Patients are progressing.
Also in the later paragraphs 'For the First Time" there is mention of LCT and how competitive they might be compared to other Stem Cell Treatments. So a detailed Business Model may not be far away...
