Characterization of spleen Z cells from naïve NOD-SCID mouse

Eight NOD-SCID mice of 6-8 weeks old were sacrificed, and spleen cells harvested. Z cells were isolated using a red fluorescent TMR-Zfra peptide in cell sorting (Oncotarget. 2015 Feb 28;6(6):3737-51). Two cell populations were isolated, which are Z(-) and Z(+) cells, or designated as ZM for negative cells and ZP for positive cells. Mouse OneArray chips (Phalanx Biotech, Inc) were used for gene expression profiling. The goal of this research is to determine the specific gene expression profile in newly isolated spleen Z cells. 8 spleen cells were sorted and isolated as Z(-) and Z(+).
