Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

How did the characteristic pattern of embryonic cell divisions during animal development evolve? Analysis of the multicellular development of an organism related to animals now provides some answers.

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 ...

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 single-celled creature originally found in shallow sea sediments around Hawaii develops into multicellular structures with remarkable similarities to animal embryos. The finding could help ...

Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...
