India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.

A new study shows that lab-grown sperm cells can be derived from stem cells. July 9, 2009 — -- The face of infertility-- in literature, in the media, in advocacy groups -- is so predominantly ...

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 ...

Two new studies uncover how DNA folding controls sperm cell development. Researchers identified proteins that rearrange genomic architecture, setting cellular memory and fate. This 3D genome mapping ...

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 have found that targeted delivery of messenger RNA (mRNA) can restore sperm production and fertility in ...

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery—how "selfish chromosomes" cheat the rules of genetic inheritance. The researchers found that ...

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...
