To evaluate the neutrophil response, we performed time-lapse confocal imaging in gent-AKI transgenic fish expressing mCherry driven by the cadherin-17 promoter, Tg(cdh17:mCherry), a renal tubule marker (Sanker et al., 2013), and enhanced GFP driven by the lysozyme C promoter, Tg(lyz:EGFP), a marker of neutrophils (Fig. 4A) (Ellett et al., 2011; Kitaguchi et al., 2009). The gene discussed is CDH17; the disease is acute kidney injury.
