	Researchers use embryonic model to reprogram malignant melanoma
		The study demonstrated the ability of malignant melanoma cells to respond to embryonic environmental cues in a chick model -- in a manner similar to neural crest cells, the cell type from which melanocytes originate -- inducing malignant cells express genes associated with a normal melanocyte.
		During embryonic development, neural crest cells display "invasive" behavior, similar to metastatic cancer cells, migrating from the neural tube (which becomes the brain and spinal cord) to form tissues along specific pathways.
		Taken together, results of this study suggest that human metastatic melanoma cells respond to and are influenced by the chick embryonic neural-crest-rich microenvironment, which may hold promise for the development of new therapeutic strategies, the researchers said.

	Gamma Protocadherin Expression in the Embryonic Chick Nervous System
		In chick, OL-pcdh was localized in ventral forebrain at early stages [12] and later associated particularly with visual brain nuclei in areas such as thalamus [11] while the pcdh-α family exhibited moderate and widespread expression in the forebrain of the later stage embryonic chick [13].
		In embryonic mouse spinal cord, expression of the pcdh-γ family was widespread in gray matter, but preferentially associated with the dorsal horn in the adult [20] and appropriate spinal cord interneuron survival and synapse formation or maintenance have been demonstrated dependent on the pcdh-γ family [8, 9].
		Expression in the chick floorplate as seen with the pcdh-γ constant region in situ hybridization probe used in the present study was not observed earlier for γA-like pcdh [14], but in mouse, pcdh-γ isoforms and pcdh 15 have been reported in floorplates of brain ventricles [24] and the neural tube [25].

	The Anatomy of the Embryonic Disc
		The embryonic disc is the mass of cells that sits on the surface of the yolk and gives rise to the chick and its extra-embryonic membranes.
		The embryonic disc is also called the blastoderm, the blastodisc, the disc of blastomeres or, at later stages, the blastula.
		The first diagram shows the embryonic disc as it sits on the yolk and the plane of section of the slides you will be viewing.

		Partially purified factor from embryonic chick brain can provoke neuralization of Rana temporaria and Triturus alpestris but not Xenopus laevis early gastrula ectoderm.
		The corresponding protease-sensitive agent was extracted, partially purified by chromatography on DEAE-Toyopearl and Heparin-Ultragel columns, and its neuralizing activity was tested in vitro on ectoderm isolated from early gastrulae of R. temporaria, Triturus alpestris, and Xenopus laevis at different concentrations and for different periods of time (animal cap assay).
		The results are discussed in relation to the neural competence of amphibian ectoderm and the mechanisms of neuralizing actions of different factors which might be involved in neural induction and patterning.

	Differences in the extent and heterogeneity of lysyl hydroxylation in embryonic chick cranial and long bone collagens. (Site not responding. Last check: 2007-11-03)
		The hydroxylation of lysine in embryonic chick long bone and mandibular collagen was found to be approximately 3-fold greater than that of the collagens of adult animals.
		The relative proportion of the three peaks changed as a function of embryonic age and maturation: more of the alpha 1(I) chains with the highest hydroxylysine content was present in the collagen synthesized earliest during embryonic development.
		This is consistent with results which demonstrated that the collagens synthesized earliest during embryonic and postnatal development had the highest hydroxylysine contents.
