From: Role of tumor cell senescence in non-professional phagocytosis and cell-in-cell structure formation
Heat-treated cells (56 °C, 45 min) were engulfed by non-professional phagocytes. Heat-treated cells stained red with CTFR and living cells stained green with CTOG. Nuclei stained blue with DAPI. a Normal epithelial lung tissue cells BEAS2B. b Different phases of cell attachment during phagocytosis in BEAS2B lung epithelial cells. c Cell-in-cell rates in different primary fibroblasts and tumor cell lines. Z-stack images were acquired by optical sectioning of 60 images. Image planes of the X, Y and Z plane are included. d BEAS2B epithelial lung cells and e SBLF-4 primary fibroblast. Instead of the CTOG staining the α-tubulin staining was used. Scale bars: 10 μm
