Labeled cells were imaged using an LSM 780 confocal microscope (Carl Zeiss). Images were processed using Photoshop CS2 software (Adobe Systems). Choroidal vascular density was analyzed using ImageJ software (NIH) as described previously (Le et al., 2010 (link)). Fluorescence intensity was quantified using Zen Black software (version 2012; Carl Zeiss) according to the manufacturer’s instructions. All images shown are representative of three to eight independent experiments.
