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 ...

Building on previous efforts to create a platform for the extended study of primate embryos in cell culture, two new reports from the State Key Laboratory of Primate Biomedical Research, Kunming ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

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 ...

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 ...

A human embryo model replicates key early developmental processes and generates organ-seed cells in vitro. [Photo provided to chinadaily.com.cn] Chinese researchers have developed a first-of-its-kind ...

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, ...

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 ...
