Fig 1: Immune cell subset characteristics in the tumor microenvironment. (A) Multiple fluorescence immunohistochemical images for tumor (panCK, Abcam, ab7753), T cells (CD8, Abcam, ab178089), macrophages (CD68/HLA-DR, Abcam, ab213363/Abcam, ab92511), and NK cells (CD56, Abcam, ab75813) in the vaginal stump bump sample. Multiplex stained slides were scanned using a Vectra Polaris Quantitative Pathology Imaging System (Akoya Biosciences) at 20 nm wavelength intervals from 440 to 780 nm with a fixed exposure time and an absolute magnification of ×200. (B) Quantitative analysis of the immune composition in the tumor and stroma. (C) Percentage of immunoreactive cells in the tumor component. panCK, pan-cytokeratin; CD8, cluster of differentiation 8; CD68, cluster of differentiation 68; HLA-DR, human leukocyte antigen-DR isotype; CD56, cluster of differentiation 56.
