I don't know enough about leukemia to say with certainty. I suspect that if they are in remission or 'cured', then the cells would be useful. I also imagine that certain gene-editing or even cell-selection technologies could be applied to the cells ex vivo, so if there is a genetic component that can be corrected for, they might be useful in that way. I've wondered if there are any studies that are harvesting the stem cells of patients with blood cancers, selecting out the non-cancerous ones, and expanding those cells for an autologous transplant after chemo-ablation of their cancerous ones. I'll have to look into it. Thanks, I did. Fixed.Serious question and no intent to nit-pick: is it the case of some subtle English thing about contexts, or did you mean to write 'cognitive deficits alleviation/reversal' but missed it?
