Stem cell-based therapies Q&A-Fate of transplanted cells

I received an intelligent and important question yesterday.

Q: iPS cell-derived insulin-producing cells may be attacked again by autoimmune cells in Type 1 diabetes. iPS cell-derived insulin-producing cells and eye cells may degenerate again in Wolfram syndrome. What is the solution?

A: This is a very important question. Before we transplant iPS cell-derived cells, we need to modify disease-causing gene structure in Type 1 diabetes and Wolfram syndrome. In Type 1 diabetes, we probably need to modify insulin gene structure. In Wolfram syndrome, we need to modify Wolfram gene structure. This can be accomplished by genome editing. The genome editing technology is a new type of gene therapy. Using an enzyme and artificially designed guide RNA, we can modify gene structure. We are actively working on this.
