Good to see an organization supporting research that could lead to drug independence! Brenda Novak, the author whose Diabetes auction I have long supported told me that after a lot of research she concluded that DRI was the only group where donated money might actually lead to real cures. She has raised several million for them with the help of the Romance writer and reader communities.
Though the cells in this case are foreign, hence the need for the immunosurpressive drugs, the technique they are using for implantation could possibly someday be applied to your own cells, tweaked in some way to protect against immune attack and then grown in culture. Lots of people with Type 1 still have a small reserve of beta cells. Or they may be able to take stem cells and push them into becoming beta cells. I believe this technology is already developed.
For now they have taken a huge step in validating that their noninvasive implantation technique works.
