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, ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

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 ...

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 ...

A new model for embryo research Unlike other common laboratory animals, such as mice, guinea pigs have a preimplantation development that is more comparable to that of humans in terms of timing and ...

In vitro embryo production (IVEP) in sheep and goats encompasses a sequence of biotechnological steps: recovery of oocytes, maturation of oocytes under controlled conditions, fertilisation with ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

New biophysics research adds to our knowledge about the origins of left-right asymmetry in the body. Most animals, including humans, have bilateral symmetry, which means our bodies are pretty ...

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 ...
