Using stem cells that they extracted from the brains of diabetic lab rats, and turning them into insulin-producing pancreatic cells, Japanese scientists may be on the road to a virtual cure for diabetes that comes from people's own brains. Led by Tomoko Kuwabara of the National Institute of Advanced Industrial Science and Technology in Tsukuba Science City, Japan, a team of scientists extracted neural tissue from the rats' olfactory bulbs or their hippocampuses. The former is the part of the brain is involved with smell while the former is involved with memory.

Because of both sites' location in the brain, extraction was easily done through the nose. The rats involved had either type 1 or type 2 diabetes. The scientists then extracted stem cells from the tissue and applied a human protein to them, Wnt3a, which "switches on" insulin production.

After two weeks, the cells had multiplied to the point that the researchers could lay collagen sheets impregnated with them gently on top of the diabetic rats' pancreases. Seven days later, the concentration of insulin in the blood of all the rats, whether type 1 or type 2, matched that of non-diabetic rats. Blood glucose levels were normal.
