Colossal Biosciences, based in Dallas, has successfully created genetically modified mice designed to exhibit traits akin to woolly mammoths, including longer, golden hair and additional fat storage. These alterations are a crucial milestone in the company’s overarching goal of de-extinction for woolly mammoths. By utilizing innovative genetic modification techniques, these woolly mice could serve as an experimental model in understanding the biological changes necessary for reviving the long-extinct species. NPR's Rob Stein provides insight into the lab work leading to this groundbreaking achievement.
The genetically modified woolly mice reflect a significant step in Colossal Biosciences’ ambitious plan to eventually bring woolly mammoths back from extinction.
These woolly mice feature the long golden hair and fat reserves characteristic of woolly mammoths, showcasing advanced genetic modification techniques.
