Figure 5. Cellobiose glycopolymers impair glycocalyx barrier function in human corneal epithelial cells.

Figure 5

As determined using the rose bengal penetration assay, treatment of stratified corneal epithelial cells for 1 hour with cellobiose glycopolymers, containing either 240 or 640 repeating units, significantly impaired glycocalyx barrier function. No effect on rose bengal uptake was observed when lactose-containing glycopolymers were used. Images were obtained using a 10× objective lens. All the experiments were performed in triplicate and represent the mean ±SD. ns, not significant; ***P<0.001.
