For example, they have used stem cells to cure mice that had spinal damage a few years back, and there's evidence that suggests that it might work on people... BUT stem cells are such a hot button topic that it's unlikely that they'll use it as the reason for Babs' cure.
Also, aside from any ehtical issues, the mice was had their spinal cords neatly sliced with a scalpel - that's much less messy than having a whole chunk destroyed by a speeding bullet. I think the new nerve growth only needed to bridge a gap of a few millimetres or less.
If I remember correctly, any bigger a gap than that and the axons don't reach the correct destination site and the spine ends up wired up all doolally and functionally useless.
