Identity and functionality of macrophages. Macrophages engulfed dead cell parts (shown in green), imaged with Cell-IQ (Chipman technologies). In image a in the first time point, the well of cell culture plate is still full of small particles seen as fuzzy green background. b At 5 h time point, the background is clean, because macrophages have engulfed the dead cell debris. c Double positive macrophage (CD68-FITC (green) and CD11b-V450 (blue)). d Hematoxylin–eosin stained macrophages isolated from adipose tissue. Nuclei of the macrophages marked with arrowhead. c and d obtained with Nikon Eclipse TS100 inverted fluorescence microscope and digital sight DS-U2 –camera. Scale bar 50 µm
