Fig. 5From: Differential activation of RAW 264.7 macrophages by size-segregated crystalline silicaTo help understand how particle size affects the production of reactive oxygen species in the mitochondria (mROS) in AM we exposed AM to both UF (a) and C (b) particles over a 3-h exposure period and measured mROS production using the superoxide indicator MitoSOXâ„¢ Red. mROS production is demonstrated over three hours in these representative images using original magnification x10, of the live cell experiment collected at 0, 1, 2 and 3Â h, by increase in fluorescenceBack to article page
