Title:
THERAPEUTIC COMPOSITION CONTAINING CORNEAL ENDOTHELIUM REPLACEMENT CELLS
Document Type and Number:
WIPO Patent Application WO/2023/282337
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a therapeutic composition, in particular, a transplant therapy composition, which allows for cryopreservation without damage to cells due to thawing, and which can be administered to a patient without undergoing an additional process such as washing or centrifuging the thawed cells. A therapeutic composition for transplantation, the therapeutic composition containing corneal endothelium replacement cells that have a CD24-positive phenotype, a phenolphthalein derivative, and a cryoprotectant. Despite containing the cryoprotectant, this therapeutic composition is capable of safe intraocular transplantation. Due to being CD24-positive, the therapeutic composition is expected to have the effect of avoiding phagocytosis.
