Mission/Background :
Caksus Bio Inc. is a regenerative medicine startup originating from Keio University. The company develops regenerative medicine products based on iPSC-derived corneal endothelial substitute cells for the treatment of bullous keratopathy. Its mission is to overcome donor shortages and limitations of conventional corneal transplantation through innovative cell therapy technologies, expanding access to treatment for patients worldwide.

Technology & Business
Caksus Bio develops proprietary technologies for the efficient differentiation and large-scale production of corneal endothelial substitute cells from induced pluripotent stem cells (iPSCs). Its cell injection therapy aims to restore corneal endothelial function without requiring donor corneas, potentially reducing surgical complexity and improving patient access to treatment. The company is also advancing manufacturing, quality control, and commercialization capabilities for regenerative medicine products.
