Fig. 2. Immunohistochemical staining of FOXP3 in the LF of terminal ileum and cecum in the control group (A-D) and the Crohn's disease group (E-H). Scale bars = 100 µm (A, C, E, G) and 50 µm (B, D, F, H). (I, J) Quantification of FOXP3 positive cells performed using three lesions showing the most representative expression of each patient in (I) terminal ileum and (J) cecum. Data are represented as means ± standard error.

FOXP3⁺ = forkhead box P3, LF = lymphoid aggregates or follicles.
