FIGURE 7.
Images of CD45-IR leukocytes (top panels) and IBA1-IR macrophages and monocytes (bottom panels) in cytokines-induced colitis model from a representative human colon specimen. CD45-IR leukocytes (A–D) are densely and IBA1-IR macrophages (E–H) moderately localized in the lamina propria area. Note, in the TNFα and IL-1β treatment tissues, CD45-IR leukocytes migrated to the damaged crypts (indicated by ∗ in B) and more IBA1-IR macrophages were found aligning the damaged epithelium (indicated by ∗ in F). The scale bar represents 50 μm. C, crypt; Epi, epithelium; LP, lamina propria. All images were taken from the colonic mucosa of a 50-year-old female patient.
