Fig. 6From: Real-time monitoring of liver fibrosis through embedded sensors in a microphysiological systemZO-1 expression in Liver MPS and liver fibrosis-on-chip with different ECM. The control Liver MPS (without TGF-β1 stimulation) shows better ZO-1 (green color) (tight junction protein) formation. While in the liver fibrosis-on-chip model, the ZO-1 distorted. The images were taken at the termination of the experiments at 144 h (scale bar is 200 µm)Back to article page
