Research Summary

Center/Research Area Affiliations


An internationally trained scientist, Dr. Baranov is committed to the development of stem-cell based and molecular therapies for blinding diseases. He is designing drug-screening assays by combining pluripotent stem cell biology with tissue engineering and imaging tools. He also works on collaborative projects involving the differentiation and transplantation of pericytes and retinal ganglion cells. This work is based on his previous studies that have demonstrated that human retinal progenitor cells can be expanded in vitro, while maintaining the capacity to form photoreceptors. This finding contributed to the development of a cell-based therapy for retinitis pigmentosa.
