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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...

Researchers at the University of Connecticut have reported a novel bovine embryonic stem cell line with improved pluripotency ...
