The pathway to EMT in mannitol treatment (IMAGE) Tokyo Metropolitan University Caption Hyperosmotic stress leads to a reorganization of actin structure in tubular epithelial cells, with elevated incorporation of alpha-SMA and reorganization of focal adhesions. This leads to EMT, as evidenced by a decrease in E-cadherin expression.
