Biochemical ‘DNA methylation’ marks are found across the genome in vertebrate animals, but in the early embryos of placental mammals, such as mice and humans, they are largely erased in a ‘system ...

In mammals, signalling between the placenta and the embryo is essential for successful development. Here, a quantitative, time-resolved model describes the coordinated formation of the mouse embryo ...

A cell of the ichthyosporean C. perkinsii showing distinct signs of polarity, with clear cortical localization of the nucleus before the first cleavage. Microtubules are shown in magenta, DNA in blue, ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

CRCHUM researcher Sophie Petropoulos and her team reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of ...

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 ...
