Results
enhancement
engineered cells boosted the return of corneal clarity more than standard therapy
More results

The therapeutic potential of mesenchymal stem cells (MSCs) in regenerative medicine is frequently thwarted by hostile post-injury microenvironments characterized by oxidative stress, inflammation, and rapid clearance, which compromise cell survival and paracrine efficacy.

More results

Using corneal chemical injury as a rigorous proof-of-concept model, this platform demonstrated unprecedented regenerative potency.

Conclusion

This work presents a transformative paradigm in nanomedicine, shifting the focus from passive cell delivery to active microenvironmental modulation, thereby offering a versatile and scalable strategy for next-generation regenerative therapies across diverse clinical indications.
