Representative photomicrographs of the lung parenchyma of animals from the silica group (a) and the SIL group treated with cells (b) or EVs in two different doses: EV5 (c) and EV6 (d). Slices were stained with hematoxylin–eosin staining. Arrows indicate granulomas, 200×. e Fraction of area of granuloma in the lungs, quantified by analysis of photomicrographs of 5 animals per group, represented as a percentage of the total area of lung tissue. *Significantly different from SIL-Sal, p < 0.05
