Figure 2.

Flow cytometric analysis for cell surface and intracellular expression of the cluster of differentiation (CD) 74, macrophage migration inhibitory factor (MIF), and CD44 in the breast cancer cells displayed. Empty histograms represented the expression of CD74, MIF, and CD44. Expression in Raji, Jurkat, and HeLa cells is used positive controls, whereas blue-filled histograms were shown as a negative control obtained from isotype matched with control antibody. The data are representative of three independent assays
