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 ...
Almost every type of human cell is powered by mitochondria, bean-shaped organelles that use oxygen to synthesize usable energy.* These structures evolved billions of years ago from free-swimming ...
In which we meet the pioneers of one of the most exciting — and controversial — fields of biomedical research: in vitro gametogenesis, or IVG. The goal of IVG is to make unlimited supplies of what ...

Micro-RNA in sperm proves vital for human embryogenesis
The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that ...
Even after decades of research, biologists are still uncovering surprises about the human body. A team of researchers from the University of Virginia and the National Institutes of Health (NIH) have ...
Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...
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 ...
