Researchers at the University of Pennsylvania turned human blood cells into early sperm cells by transplanting engineered tissue onto a mouse’s kidney, according to a study published this month in ...

For now, that goal remains elusive. The lab-grown cells stopped developing at an immature stage. Many hurdles need to be ...

Egg cells missing a key protein may be more likely to end up with the wrong number of chromosomes, but an mRNA injection that ...

When Dolly the sheep—the first cloned mammal—was born 30 years ago, she became one of the most famous animals in science ...

Modern IVF treatment can now achieve substantially higher success rates than historical approaches while dramatically ...

In biomedical research using mouse models, preparing pseudopregnant recipient females is a standard step in embryo transfer ...

An extremely precise genome editing technique called base editing has been used for the first time by Cambridge scientists to ...

Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

The first moments of life are a delicate yet busy time, when one cell becomes two, then four, and a flurry of genetic cues starts orchestrating their growth. Within this process, a gene called NANOG ...

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human ...

For the second time this month, a team of researchers has reported harnessing a precise gene-editing technique to alter the DNA of human embryos. Precise genome editing of human embryos triggers ...
