Elevated anti-apoptotic shift in primary human aniridia limbal stromal cells following 48 hours supraphysiological glucose exposure, in vitro

A 48-hour exposure to 70 mM glucose induces a marked anti-apoptotic shift in human limbal stromal cells, more pronounced in cells derived from congenital aniridia patients. Together with previous evidence on TGF-β1 and NF-κB regulation, these findings suggest that limbal cells may mount an early protective response to metabolic stress, which could be harnessed therapeutically to manage aniridia-associated keratopathy through coordinated survival and stress pathways.
