Sexual reproduction provides a kind of health insurance, protecting offspring from mutant genes thanks to DNA copies from each parent. Duplicate DNA can act as a healthy backup to offset those mutant ...

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 ...

Researchers at the Centre for Genomic Regulation (CRG) in Barcelona have identified a potential new diagnostic marker that predicts the successful and efficient development of mammalian egg cells. The ...

The store that invented the Scotch egg has hatched a new scientific version – made with sausage meat grown in a lab. Posh retailer Fortnum & Mason first created the snack in 1738. And its latest ...

SCIENTISTS have created a synthetic human embryo that can survive outside the womb using stem cells. The “embryo model” was made in a lab without the need for sperm or eggs and behaves like the real ...

Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.

Why are we asking this now? Scientists in the United States led by Renee Reijo Pera of Stanford University School of Medicine have made primitive sperm and egg cells from stem cells taken from spare ...

Human eggs and sperm have been grown in a laboratory, in research that could change the face of reproduction. According to reports in the Daily Mail, the sperm had heads and short tails and are ...

Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells. There's a reason ...

The first human egg cells that have been grown entirely in the laboratory from stem cells could be fertilised later this year in a development that will revolutionise fertility treatment and might ...

Scientists report they have grown the early stages of a human embryo-like entity without using sperm, an egg or a womb. The ’embryo model’ even releases hormones that triggered a positive pregnancy ...
