With a total of eight patents to his name, Nakano's work has the potential to impact the treatment of retinal diseases.

Latest Patents

One of Nakano's latest patents is a method for producing retinal tissue and retina-related cells. This invention outlines a two-step process that begins with subjecting pluripotent stem cells to floating culture in a serum-free medium to form an aggregate. The second step involves further culturing this aggregate in a medium that is free of substances acting on the Sonic hedgehog signal transduction pathway but contains substances acting on the BMP signal transduction pathway. This innovative approach aims to obtain aggregates containing retinal progenitor cells.

Another notable patent is the method for producing a ciliary marginal zone-like structure. This invention describes a process for culturing a cell aggregate containing retinal tissue, where Chx10 positive cells are present in a significant proportion. The method emphasizes the importance of using a serum-free medium or serum-containing medium that acts on the Wnt signal pathway for a limited time, followed by a different culturing approach to achieve the desired cell structure.
