Inactivating the Fam83g, Fzd6, Tgm3, Astn2, Krt25, Tgfa, and Krt27 genes alters the growth pattern, causing it to curl, form curls, and become thicker, resembling mammoth hair.

Instead of the short, silky, and flat fur found on a typical mouse, the woolly mouse is, well, woolly. Its hair is long, slightly coarse, and more prone to matting than its non-engineered counterpart.

The George Church–cofounded de-extinction company, Colossal Laboratories and Biosciences has announced that it has successfully engineered woolly mammoth hair traits into mice. The Colossal ...

Colossal believes its research will have far-reaching effects. Besides being the first living animal engineered to express multiple cold-adapted traits using mammoth gene orthologs, these mice ...

It’s tiny, but this lab mouse could have a mammoth impact. With curly whiskers and wavy, light hair that grows three times longer than that of an ordinary lab mouse, the genetically modified ...

One, the mammoth’s curly textured hair, is quite visible. The other — altering a mouse’s metabolism to store, not burn fats — is less so. To identify what genes they might target to achieve those ...

Scientists genetically engineer mice with thick hair like the extinct woolly mammoth In this Feb 2025 photo provided by Colossal Biosciences are genetically edited mice with long, thick, woolly ...

Scientists Genetically Engineer Mice With Thick Hair Like the Extinct Woolly Mammoth WASHINGTON (AP) — Extinction is still forever, but scientists at the biotech company Colossal Biosciences are ...

Scientists began with mice to see if the process works before possibly moving on to edit embryos of Asian elephants, the woolly mammoth's closest living relative.
