Ultimately what they need to do is decipher stem cell development and fetal development and use the patient's own cells to replace the lost islet cells.

If you don't have a solution to the autoimmune aspect, then a stem-cell-based treatment is no better than one with engineered bacteria or someone else's cells. The originals are gone because the body mistakenly thought they were foreign. A treatment like the article discusses might make stem cells more viable than the alternatives, though, as they'd be less foreign, so need less immune system alteration.
