COM crystals trigger epithelial-mesenchymal transition (EMT) in renal cells. A Cell morphology. B Spindle index. C, D Flow cytometry with annexin V/propidium iodide stainings. E–H Epithelial markers (E-cadherin and ZO-1). I–L Mesenchymal markers (fibronectin and vimentin). All quantitative data are presented as mean ± SD derived from three independent experiments using different biological samples. A.U. arbitrary unit
