New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits ‘reset’ so that the newly formed embryo can develop according to its own genetic program. The study was ...

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells ...

The time immediately after the sperm and egg unite - the so-called zygote stage - seemed to be an extremely critical phase for the embryo's development. We wanted to find out why this is the case." ...

Stem cell biologist Jacob Hanna, a 2024 STATUS List member, says embryo models can be handled ethically, and can lead to advances in organ transplantation.
