Table 1 Histological scores of Von Willebrand Factor (vWF), alpha-Smooth Muscle Actin (α-SMA), Vascular Endothelial Growth Factor (VEGF), Kinase Domain Receptor (Flk-1) and ED-1-macrophage in eutopic endometrium and endometriotic lesions after15 and 30 days.

From: Higher expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2 (Flk-1) and metalloproteinase-9 (MMP-9) in a rat model of peritoneal endometriosis is similar to cancer diseases

Eutopic endometrium 8.1 ± 0.73 5.1 ± 0.73 5.68 ± 0.10 6.46 ± 0.12 7.6 ± 1.07
Endometriosis 15 days 21.5 ± 1.35a 11.3 ± 1.15a 8.52 ± 0.19a 9.81 ± 0.11a 34.2 ± 0.78a
Endometriosis 30 days 20.6 ± 0.84a 19.2 ± 1.03a b 8.43 ± 0.12a 10.31 ± 0.18a 40.2 ± 1.03a
  1. a P < 0.05 (the scores for all markers are significantly higher in endometriotic lesions compared to eutopic endometrium).
  2. b P < 0.05 (the scores are significantly higher in endometriotic lesions after 30 days for α-SMA compared to lesions with 15 days).
  3. Values are mean ± standard error.
