Also that the bone marrow of the rib bone is an excellent source of multipotent stem cells. And yes, I know that they are not pluripotent.

Grow only partially back, and only if the bone is not totally removed.    Under a slightly different set of "right" circumstances, other bones can be made to grow partially back too.

Actually, rib bones are old school, way older then the USC findings of mice by at least a decade. Hard to find outside of the case studies in medical journals. Yet, "other bones potentially, even partial, growing back" is, as you say, "cutting edge". But, the mere fact that this is so hard, regarding rib bones only, to discover is perplexing to me. Why is so little revealed when they've been doing it for so long? Rhetorical
