Purinergic signalling.Purinergic Signal.2012 Sep;8(3):503-21. Epub 2012 Jan 25.
Components of purinergic signalling are expressed in the early embryo raising the possibility that ATP, ADP and adenosine may contribute to the mechanisms of embryonic development. We summarize the available data from four developmental models-mouse, chick, Xenopus and zebrafish. While there are som

The cranial neural crest (CNC) is a population of cells that arises from the lateral part of the developing brain, migrates ventrally and coordinates the entire craniofacial development of vertebrates. Many molecules are involved in CNC migration including the transmembrane metalloproteases ADAM13 a

… Several pioneering researchers revealed that Xenopus laevis embryos show this shadow response temporarily at the tail-bud stage (phylotypic late-somite stage just before larval stages). … The cement gland is an adhesive, mucous-secreting embryonic organ that characterizes this Xenopus tailbud stage embryo. … Aquatic Xenopus embryos often hang onto circumferential substrata, water grasses and even each-other's bodies. …
