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 ...

BBB National Programs’ National Advertising Division recommended, as part of its routine monitoring program, that Happy Mammoth discontinue certain health-related claims for its Hormone Harmony ...

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 ...

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 ...

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 ...

Colossal made a splash in 2021 when it unveiled an ambitious plan to revive the woolly mammoth and later the dodo bird. Since then, the company has focused on identifying key traits of extinct ...

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.
