Effect of Mesenchymal Stem Cell-Derived Exosomes on Retinal Injury: A Review of Current Findings

Figure 1

Histological findings revealing integration of mesenchymal stem cells at the level of the ganglion cell layer in the ischemic rat retina. Retina in section counterstained with Bisbenzimide, photographed with the specific filter for Bisbenzimide (left) and with the specific filter for Dil (right). CV: vitreous body; SCG: ganglion cell layer; SPI: internal plexiform layer; SNI: internal nuclear layer; SNE: external plexiform layer; ENL: external nuclear layer; PRL: photoreceptor layer; RPE: retinal pigment epithelium; MSCs: mesenchymal stem cells.
