Researchers from Pritzker Molecular Engineering, under the guidance of Prof. Jeffrey Hubbell, demonstrated that their compound can eliminate the autoimmune response linked to multiple sclerosis. Researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME) have developed
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.
