Scientists: Pig Cells May Help Human Diabetics

Researchers are studying whether pig cells may reduce the need for insulin injections in humans suffering from diabetes.

Scientists at Washington University have transplanted embryonic pig pancreatic cells into diabetic monkeys, which could have major implications for the treatment of diabetes in humans.

Dr. Marc Hammerman says the approach has reduced the animals' need for insulin injections and does not call for immunosuppression, which is a major problem in treating diabetes with transplantation.

Before DNA technology enabled pharmaceutical companies to manufacture human insulin in the 1980's, pig and cow insulin were routinely given to diabetic patients.
