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 ...

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, ...

Harvard John A. Paulson School of Engineering and Applied Sciences Gastrulation is one of the most important phases in early embryonic development. Before gastrulation, vertebrate embryos are simple ...

It's one of life's most defining moments - that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage ...

Toward the goal of generating high-quality embryo models in vitro, this study establishes a stepwise protocol to derive trophectoderm-like cells from mouse extended pluripotent stem (EPS) cells. These ...

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 ...

A synthetic embryo can now be constructed from very early pre-embryonic cells – without the need for an egg or sperm. These were initially created in mice. In April, Chinese researchers created ...

Researchers have developed a theoretical framework that can reproduce and predict the patterns associated with gastrulation in a chicken embryo. Gastrulation is one of the most important phases in ...

So even under present guidelines and regulations in many countries, if embryo models can be grown through gastrulation and beyond, it could become legal for the first time to experimentally study ...
