Converting this knowledge into useful gene therapy would be awesome, but the barriers seem huge.
I wouldn’t envy being most kids today, except for being kids talented in the sciences.
Being able to target the exact spot to cut is outstanding. The problem from a gene therapy position is delivering the "fix" to the right population of cells. The differentiation process results in sections of DNA that are active and others that are purposely "protected" to elicit the proper functioning of the cell. A snip that is beneficial to the desired target population may result in dysfunction in a different cell type.
