Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are ...

In April, researchers in China reported that they had initiated pregnancies in monkeys through a procedure seemingly much like in vitro fertilization (IVF), in which embryos created in a dish were ...

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 ...

Embryos start out as a single cell and have to go from there to a complicated array of multiple tissues. For organisms like insects or frogs, that process is pretty easy to study, since development ...

In a recent study published in the Cell journal, researchers showed that post-gastrulation synthetic embryos (sEmbryos) could be synthesized outside the uterus using mouse naïve embryonic stem cells ...

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
