When sugar levels were high, the cells produced more of a protein that beta cells release when they break down sugar; when glucose levels were low, the protein levels were low as well.

Such embedding of foreign matter isn't ideal for a treatment designed for the clinic, since changes in the genome could result in a variety of potential problems, including the formation of tumors and uncontrolled cell growth. Melton's group, as well as those in other stem-cell labs around the world, are working to substitute these dangerous genes and viruses with chemicals that might prove safer.
