Stem Cell Breakthrough Offers Diabetes Hope

ScienceDaily (Apr. 4, 2008) — Scientists have discovered a new technique for turning embryonic stem cells into insulin-producing pancreatic tissue in what could prove a significant breakthrough in the quest to find new treatments for diabetes... (link)

...The team found that the transcription factor PAX4 encouraged high numbers of embryonic stem cells -- about 20% -- to become pancreatic beta cells with the potential to produce insulin when transplanted into the body.

Furthermore, the scientists for the first time were able to separate the new beta cells from other types of cell produced using a technique called 'fluorescent-activated cell sorting' which uses a special dye to colour the pancreatic cells green.

"Research in the United States has shown that transplanting a mixture of differentiated cells and stem cells can cause cancer, so the ability to isolate the pancreatic cells in the lab is a major boost in our bid to develop a successful therapy," said Dr Cosgrove.

"Scientists have had some success increasing the number of pancreatic cells produced by altering the environment in which the stem cells develop, so the next stage of our research will be to combine both methods to see what proportions we can achieve."

Wow. Thanks for posting!
