While the first actual bionic man (or woman) might still be a ways off, the writers of the show might be impressed at this. A international team of researchers, have just taken an important step in the area of cell therapy: repairing the cerebral cortex of the adult mouse using a graft of cortical neurons derived from embryonic stem cells.
There is a long-standing puzzle in the diabetes field, only a small subset of insulin-producing beta cells in the pancreas of adult organisms can replicate (and hence contribute to beta cell regeneration in diabetes). Furthermore, this subset of replicating cells continues to decline with advancing age. This means that the typical risk for diabetes gets higher as you age, well now researchers have discovered an important piece of the puzzle.
