>Given the human body contains trillions of cells, each carrying the complete set of genes, which cells would be targeted by the therapy? Depends on the disease being treated. Obviously it would be extremely infeasible to edit all cells of all types in an adult human with existing technology. >If the CRISPR therapy targeted only cells in a certain organ or region, does this mean the person would have different sets of genes in different parts of their body? Yes that's correct and would be the case in any proposed adult humam crispr treatment. >What does this mean for any children born post-treatment? Do they inherit the new genes or are they stuck with the old crappy version? Only if the therapy edited the germline cells (sperm and egg), which would probably be unintentional.
