A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this ...

Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...

PORTLAND, Ore. — Researchers have created human embryos by taking nuclei from ordinary skin cells, placing them into donated eggs, and fertilizing them with sperm. The work is a laboratory ...

HINXTON, England — At first glance, the news sounds reassuring: sperm cells accumulate genetic mutations eight times slower than blood cells, making them among the most protected cells in the male ...

In a proof-of-concept experiment, scientists demonstrated that you can create and fertilize human eggs in the lab using sperm, genes from skin cells, and the "shells" of existing egg cells. When you ...

Scientists said Tuesday they have turned human skin cells into eggs and fertilized them with sperm in the lab for the first time—a breakthrough that is hoped to one day let infertile people have ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

In a controversial step that raises the possibility of a new kind of infertility treatment, scientists report that they have produced functional human eggs in the lab that were able to be fertilized ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

Human embryos have been developed from eggs given the DNA of adult skin cells – a feat that had previously been achieved in mice. This could one day provide a way for same-sex couples or women with ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...
