A doctor takes a sample of skin cells from the patient and isolates their DNA. Next, a donor egg cell, emptied of its
own genetic contents, is injected with the DNA from the patient. The embryo is nurtured to grow and divide into a blastocyst.
Some blastocyst cells are harvested and coaxed with growth factors to mature into insulin-producing cells. Finally, millions
of insulin-producing cells are injected back into the patient. In an ideal world, the patient's diabetes is temporarily 'reversed',
with no side effects . (Pic: adapted from Stem Cells: A Primer, US National Institutes of Health
