Colossal Biosciences Buys Cloning Leader Viagen
Colossal Biosciences acquired Viagen Pets and Equine to combine cloning expertise and de-extinction goals, enabling breakthroughs with 80% cloning success rates in endangered species.
- Colossal Biosciences acquired Viagen Pets and Equine, marking Colossal's first acquisition since its 2021 launch with Viagen operating as a wholly-owned subsidiary.
- Earlier this year, Colossal Biosciences made headlines after de-extincting dire wolves following 12,500 years of extinction and had drawn attention in 2021 for plans to bring back the woolly mammoth.
- Viagen Pets and Equine, founded 2002 , has cloned 15 species including black-footed ferret and Przewalski's horse, optimized protocols with 80% success, and biobanked over 40 species including 22 threatened.
- Viagen President Blake Russell will continue to run operations after a 25-year career, and Ben Lamm, Founder and CEO of Colossal, said the merger advances biodiversity-saving efforts.
- Combining Viagen's cloning stack with Colossal's resources could scale conservation cloning, as Viagen's cryopreservation expertise will fuel Colossal's Bio Vaults and leverage Roslin Institute of Edinburgh licensing.
