2. Figure 1
Microscopic appearance of an invasive lesion through the sigmoid muscularis, with (A) hematoxylin-eosin staining and (B) cytokeratin-22 immunostaining evidencing glands. Invasive lesions were characterized by the presence of endometriotic glands and stroma (arrows) inside surrounding organs. Scale bars = μm.

3. Figure 2
Protein gene product (PGP) 9.5 and nerve growth factor (NGF) immunostaining in baboon uteri and endometriotic lesions. PGP9.5 and NGF were immunostained in (A and B, respectively) eutopic baboon uteri, and (C and D, respectively) noninvasive and (E and F, respectively) invasive lesions. E and F represent glands inside surrounding organs. Glands could be followed along serial sections from the initial lesion. Scale bars = μm (A, C), 50 μm (E), and μm (B, D, F).

4. Figure 3
Nerve fiber densities. Nerve fiber density (NFD) was measured in (A) eutopic baboon endometrium and lesions, as well as (B) their direct environment (<1.5 mm). *P < .05; ***P < .001.

Nerve growth factor (NGF) expression analysis. NGF expression was scored for baboon (A) glands and (B) stroma. *P < .05.

Photomicrographs illustrating negative control samples: protein gene product (PGP) 9.5 immunostaining of an endometriotic lesion processed (A) with nonspecific IgG instead of the primary antibody and (B) with anti-PGP9.5 antibody; nerve fiber density (NFD) immunostaining of an endometriotic lesion (C) with nonspecific IgG instead of the primary antibody and (D) with anti–nerve growth factor (NGF) antibody.
