A proteomic comparison was made between SVZ and HPC cultures for differentially expressed proteins using ‘Silac’ technology that discriminates proteins synthesized in culture incorporating ‘heavy’ amino acids. Data were obtained for 840 proteins. Twelve of these were shown to be upregulated >1.4 fold in SVZ and 11 were shown to be upregulated >1.4 fold in HPC (p<<0.05, n = 3). Column 4 indicates whether this upregulation is reflected in the RNA microarray data (bolded ratios are those that are not).
