Viability of RAW 264.7 macrophage-like cells determined by LDH-Glo™ Cytotoxicity Assay, normalised to RAW 264.7 macrophages grown directly on TCP. The mean ± SD percentage viability for RAW 264.7 macrophages incubated on CTL samples was 95.8 ± 2.6% and HTE samples was 94.0 ± 4.2% (mean ± SD), p = 0.57, n = 3 (3A). The confocal images of RAW 264.7 macrophages incubated on the CTL (3B) and HTE (3C) for 48 h, stained with LIVE/DEAD™ Viability/Cytotoxicity Kit, for mammalian cells (scale bars = 30 μm).
