However, it has to be noted that a particular α-bungarotoxin-insensitive α7 nAChR was found to mediate enhancement of GABA release from chick central nervous system [16], and that rat hippocampal α7 and β subunits can co-assemble to form functional heteromeric receptors [17], [18].
In this study, we investigated the expression and function of cHES6-1 and show that it is expressed in all three germ layers of the chick embryo, particularly in the nervous system, heart, and pancreas.
Recently, some studies have shown that 5-ethynyl-2'-deoxyuridine (EdU) incorporation can serve as a novel alternative to the 5-bromo-2'-deoxyuridine (BrdU) antibody detection method for detection of DNA synthesis in regenerating avian cochlea, chick embryo and the adult nervous system.
These results suggest that the endogenous opioid peptides have an important role for feeding behavior in the central nervous system of chicks.
The alterations of these structural proteins indicate that fasting may induce changes in the fundamental structure of the nervous system in chicks, which may be especially relevant at the young age studied in the present research (5 days post-hatch).
All treated-chicks recovered from the central nervous system depressant effect of metoclopramide without any observable adverse effects.
To strengthen the physiological relevance of the hNPs-derived PNS neurons produced in culture we tested the potential of hNPs to produce human PNS neurons within the developing nervous system of the chick embryo.
The data suggest that metoclopramide induces central nervous system depression in chicks, and the drug could have potential clinical applications as a sedative-hypnotic agent in avian species not intended for human consumptions.
We also identified a possible frizzled family receptor-10 (ID: 168924), which is also significantly up regulated from 7 12 HPF, and is involved in limb and nervous system development in chicks [ 29].
dmrt genes have been detected in the central nervous system (dmrt3 in mouse, chick and medaka; dmrt4 in mouse, Xenopus, medaka and platyfish; dmrt5 in mouse, platyfish and zebrafish; dmrt6 in mouse), nasal placodes (dmrt3 in mouse and chick; dmrt4 in Xenopus and platyfish; dmrt5 in platyfish) and in the somites (dmrt2 in mouse, chick and fish; dmrt3 in chick) [32].
