From: Exogenous activated NK cells enhance trafficking of endogenous NK cells to endometriotic lesions
Density of endogenous and exogenous NK cells at sites of endometriosis. Endometriosis tissue was cut and stained as described in the legend to Fig. 6. (a) Endometriosis lesion from control animal (no treatment) (b) Endometriosis lesion from animal that received PEG-IL2 only. (c) Endometriosis lesion from animal that received i.v. A-NK cells by the i.v. route. (d) Endometriosis lesion from animals that received i.p. injection of A-NK cells. Image resolution 20X. Slides were stained with Hoechst 33342 (for nuclei). (e) Exogenous and endogenous NK cells were identified as PE-positive and Alexa 488-positive, PE-negative cells, respectively, and counted. Results are presented as mean number of cells/field of vision ± SD. Endogenous NK cells (black columns), exogenous A-NK cells (gray columns)
