Rare subpopulations of human tracheal cells are epithelial. Primary human tracheal cells were triple stained for the epithelial-specific marker CD326/EpCAM (α-CD326-FITC), the hematopoietic-specific marker CD45 (α-CD45-APC), and the marker of interest (PE-conjugated). The epithelial cells in the triple-stained population were first identified by applying a CD326-positive/CD45-negative gate (A). A PE-positive gate was created after compensation with the appropriate FMO controls to account for overlap between FITC and PE channels, and was applied to the CD326-positive/CD45-negative cells in the triple-stained populations shown in (B).
