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 ...

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 ...

Oh, brave new world, that has such embryos in it. In a dramatic scientific first, researchers have created synthetic human embryos without using sperm or an egg. No one knows if these embryonic ...

In the new study, the team used the model to demonstrate that as Alzheimer's pathology accumulates in the brain, specific types of immune cells called CT8+ T Cells surge into the brain and amplify the ...

Sex cells made from scratch could revolutionize human reproduction. But researchers are struggling to translate promising ...

In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

REHOVOT, Israel, Sept 7 (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into ...

Most potential oncology drugs fail during the drug development pipeline, even when there has been promising data for their efficacy during the in vitro stage. This makes it vital to identify in vitro ...
