FIG. 3.

Confocal images of PPCs showing rhodopsin expression (green fluorescence). PPCs cocultured with rodent neurosensory retina (A–F) or human retina (i–vi) for 1 week and identified by red CellTrace dye (nuclei detected with Hoechst 33342). To confirm that rhodopsin expression was within and not on-top of or behind PPCs, confocal images were processed so as to show individual groups of PPCs rotated through 360° (images A–F and i–vi). The arrow points to a specific rhodopsin signal. Scale bar=7 μm. Color images available online at www.liebertpub.com/tea
