(A and B) Immunohistochemistry of uterus, egg envelope and placenta for IL-1 β shows leucocytes (leu) of both mother and fetus as positive, uterus (ut), egg envelope (ee) and yolk sac ectoderm (ec) negative while the endoderm (en) is modestly positive. (C) Immunohistochemistry of paraplacenta for IL-1 β demonstrates positive staining in the surface epithelium (e) while the mucous component (m) is negative. (D) Immunohistochemistry of the umbilical cord for IL-1 β shows cytoplasmic vesicles of the epithelium (e) as positive and the microvilli (mv) negative.
