1. A method of identifying L/M-Opsin and CRX positive cone photoreceptor cells in a population of cells, comprising: a) detecting and determining whether or not cells in the population express CD29 or CD15-SSEA1 on cell surface; b) detecting and determining whether or not cells in the population express at least two of CD26, CD133 and CD 147 on the cell surface; and c) identifying cells as L/M-Opsin and CRX positive cone photoreceptor cells based on presence of L/M-Opsin and CRX, absence of CD29 or CD15-SSEA1, and presence of at least two of CD26, CD133 and CD147, and wherein the cells are L/M-Opsin and CRX positive, CD29 or CD15-SSEA1 negative and positive for at least two of CD26, CD133 and CD147.
