Since then, however, many investigators have unearthed molecular evidence that the genes involved in odontogenesis (tooth development) are indeed retained in chickens. A primary step in reaching ...

Studying how neural crest cells journey through the embryo, this Caltech developmental biologist has revealed how they form major cell types, including peripheral neurons, bone, and smooth muscle. In ...

IN the midbrain of the chicken embryo a close relationship has been demonstrated between aerobic glycolysis and cell division 1, from which it can be inferred that growth is dependent on aerobic ...

In a new discovery, scientists have found evidence that could answer the age-old puzzle of what came first - chicken or egg? The new results suggest that the ability to form embryo-like structures ...

The chicken-or-egg mystery has long puzzled humanity ... This cell cluster closely resembles an animal embryo in its earliest stage, known as a blastula. “Although C. perkinsii is a unicellular ...
