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 ...

Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...

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 ...

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics .. | Cell And ...

LONDON -- British scientists claimed Wednesday to have created human sperm from embryonic stem cells for the first time, an accomplishment they say may someday help infertile men father children. The ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Ultrastructure expansion microscopy of murine male germ cells reveals the fine molecular structures of centrioles (shown in the enlarged image). DNA is stained in blue and the chromosome axis in red.

A study finds that brief immune stress in male mice can leave lasting metabolic and behavioral effects in offspring through ...

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 ...
