Agent for promoting corneal endothelial cell adhesion
View Patent ↗The invention provides an agent for promoting adhesion of a corneal endothelial cell, containing a Rho kinase inhibitor, as well as a culture medium for a corneal endothelial cell, a solution for preservation of cornea, and a method of producing a corneal endothelial preparation, which includes culturing the corneal endothelial cell using the aforementioned culture medium.
1. A method of treating a corneal endothelial dysfunction associated with low cell density in the corneal endothelium, comprising a step of administering an effective amount of a Rho kinase inhibitor and corneal endothelial cells to an eye of a subject in need thereof,
wherein the corneal endothelial cells are suspended in a suspension containing a Rho kinase inhibitor,
wherein the Rho kinase inhibitor promotes cell adhesion of the corneal endothelial cells to the corneal endothelium, thereby increasing cell density and treating the corneal endothelial dysfunction, and
wherein the corneal endothelial dysfunction associated with low cell density in the corneal endothelium is bullous keratopathy, corneal endotheliitis, corneal endothelial dysfunction associated with intraocular surgery, corneal endothelial dysfunction caused by increased intraocular pressure, or corneal endothelial dysfunction caused by insufficient oxygen due to contact lenses.
2. The method according to claim 1 , wherein the Rho kinase inhibitor is at least one selected from the group consisting of (+)-trans-4-(1-aminoethyl)-1-(4-pyridylcarbamoyl)cyclohexane, 1-(5-isoquinolinesulfonyl)homopiperazine, and pharmacologically acceptable salts thereof.
3. The method according to claim 1 , wherein the eye is a human eye.
4. The method according to claim 1 , comprising administering an effective amount of a Rho kinase inhibitor in the form of an intracameral injection or intraocular perfusion fluid.
5. The method according to claim 2 , wherein the Rho kinase inhibitor is (+)-trans-4-(1-aminoethyl)-1-(4-pyridylcarbamoyl)cyclohexane or a pharmacologically acceptable salt thereof.
6. The method according to claim 5 , comprising administering an effective amount of a Rho kinase inhibitor in the form of an intracameral injection or intraocular perfusion fluid.
7. The method according to claim 5 , wherein the eye is a human eye.
8. The method according to claim 7 , comprising administering an effective amount of a Rho kinase inhibitor in the form of an intracameral injection or intraocular perfusion fluid.
9. The method according to claim 2 , wherein the Rho kinase inhibitor is 1-(5-isoquinolinesulfonyl)homopiperazine or a pharmacologically acceptable salt thereof.
10. The method according to claim 9 , comprising administering an effective amount of a Rho kinase inhibitor in the form of an intracameral injection or intraocular perfusion fluid.
11. The method according to claim 9 , wherein the eye is a human eye.
12. The method according to claim 11 , comprising administering an effective amount of a Rho kinase inhibitor in the form of an intracameral injection or intraocular perfusion fluid.
