Fig. 2From: Improving cell survival and engraftment in vivo via layer-by-layer nanocoating of hESC-derived RPE cellsEffects and characterization of layer-by-layer assembly coated on RPE cells. a Immunostaining for typical RPE markers (ZO-1, RPE65, and BEST1) in (gelatin)2/alginate-encapsulated RPE and untreated RPE cells. Scale bar 20 μm. b SEM images of untreated RPE cells, and (gelatin)2/alginate-encapsulated RPE cells after 7 days and 30 days in culture. Scale bar 10 μm. c Different magnifications of TEM images of (gelatin)2/alginate-encapsulated RPE cells and untreated RPE cells. Arrows indicate the materials on the cell surfaceBack to article page
