Regeneration process of the lung after blunt thorax trauma (BTT). Hematoxylin-eosin (HE) staining of lung tissue sections of male lean and obese C57BL/6 J mice after induction of blunt thorax trauma (n = 6). Figure shows lung tissue sections from control animals as well as lung sections from1 h, 6 h, 24 h, 72 h and 192 h post trauma. Arrow = lung tissue damage, arrowhead = lung tissue with intra-alveoli debris, thickened alveoli wall and alveoli collapse. Pictures were taken with an Olympus IX81microscope using Xcellence v.1.2. Scale = 50 μm at 40x magnification or 200 μm at 10x magnification. Abbreviations: HFD, high fat diet; ND, normal diet
