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.

Owing to the immense complexity of these processes, scientists’ understanding of the molecular and cellular mechanisms that ...

Embryonic stem cells are pluripotent, meaning that they have the ability to differentiate, or change, into many directions. Embryonic development Development starts with a fertilized egg cell, which ...

Human embryonic stem cells are found in the earliest stages of development and are capable of giving rise to all the different types of cell in the body. "This means their possible therapeutic ...

Scientists have observed a type of cell division in a prehistoric unicellular organism that resembles the embryonic ...

Amos Tanay of the computer science and applied mathematics and the molecular cell biology departments – uncovers new ...

A cell division resembling that of an animal embryo has been observed in a prehistoric unicellular organism, suggesting that embryonic development might have existed prior to the evolution of animals.

They observed that while in the initial stages, gastruloid and embryonic cells express different genes, they nevertheless ...
