A Key "Master" Protein That Declines by Half After Age 40. One Company Found a Way to Restore It.

Avaí Bio announced it has initiated manufacturing of a Master Cell Bank of genetically modified cells that overexpress the α-Klotho protein, a key anti-aging protein that naturally declines by 50% after age 40. The milestone represents a transition from research to production infrastructure for their Klothonova anti-aging platform using Cell-in-a-Box® encapsulation technology. The cell therapy sector is rapidly expanding, with the global market projected to grow from $10.4 billion to over $45 billion by 2035.
