Mammals have the power to regenerate - an exciting prospect
Mammals have the power to switch on dormant genes capable of regenerating cells, according to new research reported in Nature.
This idea has been toyed with a lot in the last year or two. In this study, researchers at Penn U. Medicine School found that wound healing in a mouse model created an “embryonic window” of opportunity. Dormant embryonic molecular pathways were awakened, sending stem cells to the area of injury. Unexpectedly, the regenerated hair follicles originated from non-hair-follicle stem cells.
IMO: The baldies may be able to enthuse! I have quite a lot of hair, not as much as David Chalmers perhaps (but who does ?), so it means little to me. But the idea of wound healing and body regeneration really sounds good, and hopefully in the medium term body regeneration will not be curtailed, often ineffectively, to the George Bests of this world.
