Expression of CD56 and NKp30 in a baboon model of induced endometriosis. a Representative micrographs depicting CD56 (A, C, E, G, I), or NKp30 (B, D, F, H, J) expression in eutopic endometrial stroma cells of baboon samples during the three time-points: pre-inoculation (A, B), 3 (C, D) and 15 months (G, H) post-inoculation of the disease and expression in ectopic endometrial lesions 3 months (E, F) and 15 months (I, J) post-inoculation (400× magnification). Graphs comparing percentage of stromal CD56⁺ (b), NKp30⁺ (c) and ratio of NKp30⁺ to CD56 (d) cells prior to inoculation (n = 5), at 3 (n = 7) and 15 months (n = 5) in eutopic endometrium after the induction of endometriosis and in ectopic lesions at 3 (n = 5) and 15 months (n = 4) after induction of endometriosis
