# Epitope editing enables safer transplantation without genotoxic conditioning

Researchers developed a method using epitope editing to allow transplanted cells to be selected in the body without the need for genotoxic conditioning. This technique could improve the safety and effectiveness of cell therapies by avoiding DNA-damaging treatments. The advance is significant for regenerative medicine and stem cell transplantation.
