2. FIGURE 1
SEM picture of the apical surface of the human endometrium. Borders (valleys) can be seen around individual cells. (A) Absence of pinopodes. Microvilli and cilia can be seen extending from the surface of individual cells. (B) Three pinopodes with smooth surfaces can be seen. Scale bars: (A) = 5 μm, (B) = 5 μm.

3. FIGURE 2
Day of the menstrual cycle (LH days seen in boxes under graph) verses pinopode score in infertile patients. (A) Each green bar in the graph represents a patient that gave only one biopsy. Other colored bars represent patients that gave ≥2 biopsies during one cycle (one color/patient). Bars with a square above them (three bars/three different patients) represent patients who went on to become pregnant in a subsequent cycle. (B) SEM pictures of pinopodes from patients on LH + 4, LH + 8, LH + 11, and LH Scale bars, upper row = 20 μm, lower row = 5 μm.

Day of the menstrual cycle verses pinopode score in regularly cycling fertile patients. (A) Numbers in bar graph indicate specific patients. (B) Pinopodes in an endometrial sample taken on LH day 0 from a fertile patient (patient #46). Scale bars (i) = 20 μm, (ii) = 10 μm.

Pinopodes detected in a patient administered depot leuprolide acetate followed by 24 days of micronized estradiol and norethindrone addback. Scale bars: (A) = 10 μm, (B) = 5 μm.
