Revivicor Inc (a spin off from the Scottish company that engineered Dolly the sheep), & Pittsburgh University researchers recently reported that injections of live pig pancreatic cells reversed Type 1 diabetes in monkeys. This has lead to a lot of excitement as you can imagine, with a potential cure for Type 1 diabetes in humans.
In the past, most transplants of this type resulted in temporary relief from diabetes, but this group has one monkey that has been diabetes free for a year without injections or special diet.
It is expected that human trials could start within 2 years.
While a lot of experts would prefer human islet transplants instead of pig tissue, the shortage of human “donors” compared to the unlimited supply of pig tissue means that pig tissue has a big advantage.
