MoreWingless/Integrated (WNT) signaling is a central pathway governing tissue morphogenesis, stem cell maintenance, and regeneration. However, its therapeutic translation has been hindered by challenges in delivering stable and active WNT ligands over long distances to target tissues and organs. Recent advances in exosome engineering offer a new solution to this problem by delivering WNT ligands via engineered exosomes, dual-ligand vesicles to achieve robust and sustained activation of WNT signaling both in vitro and in vivo. This perspective highlights how such dual-ligand exosomes overcome the biochemical and delivery barriers of WNT activation, promote liver regeneration under diverse conditions, including acute, chronic, and aging-associated injuries, and establish a conceptual framework for next-generation regenerative therapeutics. These findings mark a pivotal step toward reprogramming tissue homeostasis and rejuvenation through bioengineered signaling vesicles.
