Serum Sparks Mammal Limb Regrowth, Hinting at Regenerative Medicine
Texas A&M researchers report a two-step, serum-driven process that turns local cells into a blastema and promotes limb-like regeneration in lab mice by first reducing scarring and then providing developmental signals, using resident cells rather than external stem cells; the approach could lessen scarring and broaden understanding of mammalian healing with potential human applications.
