Recent study published in the July issue of The Journal Laboratory Investigation reveals that Stem cell like cells could be formed In Vitro from the insulin producing cells.
The study was done by Dr Rosenberg form the McGill University Health Center (MUHC) and McGill University together. They organized a study, using β-cells (beta cells) that produces insulin. 
They wanted to see whether the cells have the ability to return to more primitive state (stem like cells) or not. They were surprised to see that they have that ability. This process of returning to the more primitive state is called as “Dedifferentiation“.
These cells along with islets cells of Langerhans produces insulin and other hormones in the pancreas.
Thus concluding that by dediferentiating the beta cells in the pancreas, new functional insulin producing cells can be regrown which will help the pancreas to produce more insulin in diabetic patients.
It is believed, this step is a major leap in an extensive regenerative therapies research program based on a peptide called Islet Neogenesis Associated Protein, or (INGAP).
Recently INGAP has demonstrated in a clinical trial that it is possible to regrow new functional insulin producing cells in diabetic patients.

Manchester and Sheffield University Researchers Successfully Convert Embryonic Stem Cells To Insulin Producing Pancretic TissueMay 8th, 2008 Researches at the Manchester and Sheffield Universities have been able to identify the techniques to turn embryonic stem cells into insulin-producing pancreatic tissue. They will now be able to manipulate the stem cell to produce 'transcription factor', a protein necessary for treatment.
Researchers grow pancreatic cells succesfully from human embryonic stem cellOctober 29th, 2008 An important research, conducted by Geron scientists and collaborators at the University of Alberta, and been published online in advance of print in Cell Proliferation reveals about a successful engraftment of human embryonic stem cell (hESC) into pancreatic islet-like clusters (ILCs) in a diabetic mice. Pancreatic islet cells are the cells that normally secrete insulin in response to high levels of glucose in the blood to maintain steady levels.

Major Breakthrough In Treatment of Cancer And Regenerative MedicineMay 22nd, 2008 Recent researchers discovered a trick that is used by tumour cells to migrate round the body, causing normal adult cell to act like stem cells. "It is believed to be a major breakthrough in treatment of cancer and regenerative medicine, as large quantities of these reverted cells could be used to treat anything from spinal cord injury to liver damage without the risk of tissue rejection", as said by Robert Weinberg, a biologist at the Massachusetts Institute of Technology's Whitehead Institute for Biomedical Research and co-author of a study appearing in cell.
