The small subset of obese EC patients without T2DM (n = 5) showed a significant increase in CD56+ cells compared to those patients with T2DM (n = 6) (27 vs. 1 cells/mm2 epithelium, p = 0.034) and lean patients (n = 7) (27 vs. 10 cells/mm2 epithelium, p = 0.034) (Figure 3C, Supplementary Table S4). The gene discussed is NCAM1; the disease is type 2 diabetes mellitus.
