From: Exogenous activated NK cells enhance trafficking of endogenous NK cells to endometriotic lesions
IL-2 treatment augments infiltration of endometriosis lesions by endogenous NK cells. Fresh frozen endometriosis tissue from animals receiving Peg-IL-2 only was sectioned and stained with anti-NKp46 (or isotype control) followed by Alexa 488-conjugated donkey anti-goat antibody to identify endogenous NK cells Sections were also stained with Hoechst 33342 to reveal cell nuclei. Image resolution 20X. (a-b) Isotype control plus Alexa 488 donkey anti-goat. (c-d) Staining with anti-NKp46 plus Alexa 488 donkey anti-goat antibody reveals a substantial infiltration of the lesions by endogenous NK cells. Image resolution 20X
