University of Oregon biologists say they have opened the
window on the natural process of bone regeneration in zebra fish, and that the
insights they gained could be used to advance therapies for bone fractures and
disease.
In a paper placed online in advance of print in the Feb. 13
issue of the journal Cell Reports, the UO team shows that two molecular
pathways work in concert to allow adult zebra fish to perfectly replace bones
lost upon fin amputation.
