Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Researchers in the U.S. created monkey embryos asexually, without the use of sperm, in order to harvest stem cells from them. The company behind the research, Advanced Cell Technology, says the ...

"This now will hopefully set the stage for improved ways of differentiating these cells, make these embryonic stem cells turn into other cell types that we can use for other disea ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

For the first time, stem cells typically considered restricted to forming body tissues spontaneously formed a yolk-sac-like structure in a model of the human embryo. Stem cell models of human embryos ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

Advanced Cell Technology, Inc. has reported that company scientists have generated human embryonic stem cells (hES cells) using an approach that does not harm embryos. The technique is reported in an ...
