New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers in ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

In our cells, our DNA carries chemical or 'epigenetic' marks that decide how genes will be used in different tissues. Yet in the group of specialised ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

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, ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...
