Figure 2. CD74 is highly expressed in human gastric and colon tumors and on isolated epithelial cells.

CD74 mRNA levels measured by qRT PCR are increased in A) human gastric tumor samples and at higher levels in tissues from patients with nodal involvement, B) human colon tumor samples and at higher levels in tissues from patients with nodal involvement, and on epithelial cells isolated from human gastric and colon tumors in C) a representative flow cytometry plot and D) in compiled flow cytometry data from all samples. N = 8 for D and the mean ± standard error are shown as the results of duplicated in multiple experiments. *p<0.05.
