Wood's team studies embryo development, nutrition impacts and lab techniques to help producers achieve better reproductive ...

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

Some animals can postpone the implantation of their fertilised eggs in the uterus until conditions favourable to their birth ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

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 ...

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 ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...

Embryo development in livestock underpins global food security and genetic improvement programmes. From the first mitotic divisions in the zygote to the formation of the blastocyst, the timing, ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...
