The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide ...

Scientists from a collaboration of Australian research institutions have proposed that editing multiple genetic variants in human embryos could significantly lower the likelihood of developing complex ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

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 ...

X chromosome reactivation contributes to reducing the signs of disease in the female brain. Female cells have two X chromosomes and male cells have one X chromosome and one Y chromosome. So that the ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...

Only about one out of three conceptions leads to birth. 1 Approximately a third of embryos fail to attach to the uterus, while another third is lost after the embryo implants. “Human reproduction is ...

Destructive Human Embryonic Stem Cell Research—The term “destructive human embryonic stem cell research” means any research that involves the disaggregation of any human embryo for the purpose of ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic diseases. Although one of the two X chromosomes is ...
