Investigation of combined application of different type of cells, delivery methods with laser irradiation of retina on an animal model in vivo(rabbit eye) was the purpose of the study. An argon at 514nm and a dye laser at 577nm with were used to provide a controlled damage on the rabbit retina. Two type of human progenitor stem cells(hPSC) were tested: Mesenchymal and Neural. Four cell delivery methods were compared: Retrobulbar, Introvitreous, Subconjuctival and Suprachoroidal injections. Electroretinography(ERG) was used as a diagnostics of retina functionality. Selective immunohystochemical analysis was performed to assess cells migration and viability. Controlled laser damage on retina provides strong attracting signal for stem cells. Application of laser light enhances results of stem cells injection in posterior eye and may have benefits for treatment of different types of retinopathy and macular degeneration.
