This photo provided by researcher Katsuhiko Hayashi shows mice derived from stem cells, four weeks after their birth, in Osaka, Japan in September 2021. In a study published Wednesday, March 16 ...

On Tuesday, Colossal announced that its scientists have simultaneously edited seven genes in mice embryos to create mice with long, thick, woolly hair. They nicknamed the extra-furry rodents as ...

The new study investigated two species of mice. One is the most abundant mammal in North America — the deer mouse (Peromyscus maniculatus), which ranges from Alaska to Central America.

To create mice with two fathers, the researchers targeted 20 of these imprinted genes in male embryonic stem cells, using CRISPR to delete or modify them. They then combined these edited cells ...

The mouse was thought to be extinct for 20 years until tiny, isolated populations were rediscovered in 1994 in Dana Point in Orange County but the species remains endangered, the alliance said.

There are some other drawbacks — the success rate of cloning mice from cells stored in liquid nitrogen or at ultra-low temperatures is between 2 and 5 percent, while the freeze-dried method is ...
