GDF15 KO mice show greater levels of tubular damage and cardiac injury, and increased neutrophil infiltration. Sixteen hours after LPS treatment, kidneys and hearts were harvested from mice. Tissues from all groups were sectioned and stained with H&E and detected MPO activity. Images were taken from kidney cortex at 200 X magnification. (A) Representative HE staining images of kidney tissues. (B) Injury score for kidney tissues. (C) Representative MPO images of kidney tissues. (D) MPO score for kidney tissues. (E) Representative HE staining images of heart tissues. (F) Injury score for heart tissues. (G) Representative MPO images of heart tissues. (H) MPO score for heart tissues. n = 6 for HE staining. n = 4 for MPO assays. *P ≤ 0.05.
