The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

used mouse stem cells that are commonly grown in the lab to guide them to form basic building blocks of the embryo. The team used a version of CRISPR technology known as an epigenome editor ...

Scientists at Colossal Biosciences have achieved a milestone to resurrecting the woolly mammoth: laboratory mice with thick, ...

In a potentially major breakthrough for regenerative medicine, scientists at MIT have developed a way to convert skin cells ...

Cloning the mammoth is impossible. What is left of the giant mammal is found in fragments, echoes of the past. Instead of a complete replica, Colossal aims to piece together DNA from other animals ...

Converting one type of cell to another—for example, a skin cell to a neuron—can be done through a process that requires the ...

First Mouse ... embryo that acts like a navigation system, directing cells where to build the spine and nervous ... Brain Cells Remain Healthy After a Month on the International Space Station ...

Scientists with the company Colossal have created genetically engineered "woolly mice" with thick, golden-brown hair and fat deposits similar to those of cold-adapted woolly mammoths.

used mouse stem cells that are commonly grown in the lab to guide them to form basic building blocks of the embryo. Programmable cellular models of embryos, known as embryoids, allow scientists to ...
