FIGURE 1 Example of MECA-79 intensity scores (range 0–2) for the endometrial surface cellular apex (A and B). (A) received a score of 1 and (B) received a score of 2 (magnification, ×400). (C) Illustration showing the two regions (apex and cytoplasm) that receive immunohistochemical scores for the L-selectin ligand. (D) Illustration showing the two regions of endometrial epithelium (surface and gland crypt) that receive immunohistochemical scores for the L-selectin ligand. Comparison between HECA-452 (E) and MECA-79 (F) expression in endometrial tissue obtained from the same patient. Note the greater cytoplasmic expression with HECA-452 and greater apical expression with MECA-79. Shamonki. L-selectin ligand expression and pregnancy. Fertil Steril 2006.
