This study was performed on White Leghorn chick hatchlings ( Gallus gallus; post-hatch day 0-4). The first sample type was collected specifically from the NL cell group under a laser micro-dissection microscope (LMD-6000; Leica Microsystems). The second type of tissue sample was collected from the dorsal brainstem at the caudorostral level of NL. Protein preparation was performed, followed by trypsin digestion and peptide purification for mass spectrometry.

Mass spectrometry (MS)

The LTQ-FT Ultra (ThermoFisher Scientific) mass spectrometer was used. Spectra were matched to peptide sequences using SEQUEST. Peptide-spectrum match and peptide identifications were obtained from Percolator (v2.01). Peptides with Percolator with q-value <0.01 were given as input to ID Picker for protein identification. We used a decoy database using scrambled Gallus gallus genome sequence (build 12/17/11). We required at least 2 peptides per protein, each with a q -value (false discovery rate) of <0.01. At least four biological replicates with three technical replicates each were performed. We required each peptide to present in every technical replicate (n=3) and at least 2 peptides per protein for identification.

          Several software programs were used to perform gene ontology analyses of the identified proteins. The first is the DAVID Bioinformatics Resources 6.8 ( https://david.ncifcrf.gov/ ). We used this resource for protein functional annotation and gene ID conversion. Ensembl Bio-mart software ( http://www.ensembl.org/biomart/martview/ ) was also used for gene ID conversion. For identifying transmembrane proteins, we used the TMHMM program version 2.0 located at: http://www.cbs.dtu.dk/services/TMHMM/ . Finally, we used the Ingenuity pathway analysis at http://www.ingenuity.com/ as an alternative approach to DAVID for identifying enriched pathways.
