Researchers Discover Pure Insulin Cells That Treat Diabetes

These pure insulin-producing cells have the same sub-cellular structures as the insulin-producing cells found in the pancreas, These pure insulin-producing cells have the same sub-cellular structures as the insulin-producing cells found in the pancreas, Singapore's Agency for Science, Technology and Research (A*STAR) announced Thursday.

The agency said the findings were made by researchers from the Institute of Medical Biology (IMB) under A*STAR and the Yong Loo Lin School of Medicine (YLLSoM ) at the National University of Singapore (NUS).

The researchers were co-led by Dr Lim Sai Kiang, a principal investigator with IMB and a research associate professor at the Department of Surgery, YLLSoM, and Dr Li Guodong, a research associate professor at National University Medical Institutes of NUS.

A*STAR said experiments by Dr Lim and Dr Li's group showed that when transplanted into diabetic mice with high blood glucose levels, the pure insulin-producing cells would cause the blood glucose levels of the animals to decrease.

The experiments also showed that the subsequent removal of the transplanted cells from the diabetic mice would restore the blood glucose to its original level.

It was also discovered that none of the diabetic mice involved in the transplants developed 'teratoma', a type of tumor often associated with embryonic stem cells which could complicate their use in therapeutic treatment.

The pure insulin-producing cells also managed to retain their insulin-production and glucose-sensing capacity over time.

A*STAR said the researchers' achievement provided proof of the principle that this strategy could be applied to human embryonic stem cells to obtain similar pure insulin-producing cells.

The research findings have been published in two papers in this year's online version of the journal, 'Stem Cell Research'.

DID YOU KNOW: 
Cost of Diabetes Rises to $218 Billion a Year: From just a year ago, the cost for diabetes was $173 billion.  For 2007 the cost as risen to $218 billion US dollars.  A new study, puts the total at $218 billion last year-the first comprehensive estimate of the financial toll diabetes takes.
