Lady Gaga AI Biotech Startup Keeps Human Skin Alive for 4 Weeks

Michael Polansky, the singer's fiancé, co-founded the company and runs it as chief executive. Gaga, born Stefani Germanotta, sits on the board. Backers have committed roughly $23 million.

Lady Gaga AI Biotech Venture Turns Surgical Waste Into Training Data

Skin removed from the body normally dies within a week. Outer Bio's platform, named Yuna, stretches that window to four weeks. Researchers can therefore track slow biology such as collagen breakdown, inflammation, and cellular aging.

Tissue reaches the lab within hours of surgery, mostly leftover material from cosmetic procedures. Donors span every age group, both sexes, and all six Fitzpatrick skin tones.

That matters because regulators have turned against the old default. The FDA issued a roadmap in April 2025 to cut unnecessary animal testing, then reported first-year progress this April. More than 90% of drugs that clear animal studies still fail in human trials, the agency notes.
