Lipid raft-targeted Akt promotes axonal branching and growth cone expansion via mTOR and Rac1, respectively.

30 Oct 2009 The molecular mechanisms by which extracellular guidance cues regulate axonal morphology are not fully understood. Recent findings suggest that increased activity of the protein kinase Akt promotes dendritic branching and elongation in hippocampal ... Read more...

Stanniocalcin 2 promotes invasion and is associated with metastatic stages in neuroblastoma.

30 Oct 2009 Stanniocalcin 2 (STC2) is a secreted glycoprotein of as yet unknown functions. We investigated STC2 in human neuroblastoma, the most common solid extra-cranial tumor of infancy. In primary tumor samples, we found that expression of STC2 is ... Read more...

The human skin/chick chorioallantoic membrane model accurately predicts the potency of cosmetic allergens.

21 Oct 2009 The current standard method for predicting contact allergenicity is the murine local lymph node assay (LLNA). Public objection to the use of animals in testing of cosmetics makes the development of a system that does not use sentient animals highly ... Read more...

Technical information about 'Chick Embryo'

Definition: The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.

Descriptor UI: D002642

Alternative terms: Chick Embryo; Embryo, Chick; Chick Embryos; Embryos, Chick;
