One of the genes molecular targets, for example, is a microRNA (a small noncoding RNA molecule) called let7, which in turn regulates hundreds of other genes, so the effects of Lin28a can set off a complex array of regulatory interactions. Once the animals were more than 5 weeks old, they weren't able to regrow those parts, even when Lin28a function was stimulated.

This healing power means Cap's body goes far beyond regenerating burnedskin, broken bones, lost limbs, and organs, right down to the level of damaged cells.
