It is no longer science fiction: human embryos have now been made from DNA in skin cells that were fertilised with sperm, a ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive ...

In tissue biopsies, cancer cells are frequently observed to have nuclei (the cell's genetic information storage) that are ...

More work needs to be done to create viable human embryos, but the method might someday be used in IVF to help infertile people and male couples.

The embryos weren’t used to try to establish a pregnancy, but the researchers behind the technique say it could one day be ...

Another protein central to this process is NuMA, which is essential for spindle pole organisation. Normally, NuMA gathers at ...
