A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...

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 ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A 3D uterus embryo implantation simulation chip developed by a Chinese research team has, for the first time, fully replicated the entire process of human embryo implantation in a laboratory setting, ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

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 ...
