Fig 4. Polarization of the ARPE-19 monolayer.

Fig 4

Z-projections (XZ and YZ) from apical side to basal side and maximum intensity projection of the XY plane in the ARPE-19 monolayer represent the localization of Zonula Occludens (ZO-1, red) in the confocal micrograph after immunofluorescence labeling with the nuclear label 4’,6-diamidino-2-phenylindole (DAPI, blue). Scale bar is 10μm.
