Figure 2. IL-33 protein expression in the umbilical cord of normal term pregnancies.

Figure 2

(A) IL-33 is expressed in the umbilical artery (B) and Wharton’s jelly (C). x100 magnification. (B) IL-33 is expressed in the nuclei of endothelial (arrowhead) and smooth muscle cells (arrow) in the umbilical vessels. x200 magnification. (C) IL-33 is expressed in the nuclei of stromal cells in the Wharton’s jelly (inset). x100 magnification. (D) Immunofluorescence staining of procollagen (red), IL-33 (green) and DAPI (blue) shows cytoplasmic IL-33 staining in myofibroblasts in the Wharton’s jelly. x630 magnification. (E) Immunofluorescence staining of CD14 (red), IL-33 (green) and DAPI (blue) shows cytoplasmic IL-33 staining in macrophages in the Wharton’s jelly. x630 magnification. UA = umbilical artery; WJ = Wharton’s jelly.
