  • Publication number: 20230000760
    Abstract: Compositions for treating an ocular disorder are provided. The composition includes an effective amount of a human trabecular meshwork stem cell (TMSC) secretome, wherein the effective amount is present in an amount to reduce impairment of retinal ganglion cells (RGC). Methods for treating ocular disorders using the disclosed compositions are also provided. The compositions reduce and prevent cell apoptosis, axon loss, vision loss, increased intraocular pressure, and dysregulated aqueous humor outflow of a subject when used in accordance with the methods disclosed herein.

  • Patent number: 10004766
    Abstract: Provided herein are isolated populations of multipotent stem cells capable of differentiating into trabecular meshwork (TM) cells, methods of obtaining an isolated population of TM cells, and isolated populations of TM cells obtained therefrom. Compositions, kits, and devices comprising the isolated populations of multipotent stem cells or TM cells are also provided herein. Further provided are methods of using the compositions, kits, and devices for decreasing intraocular pressure in an eye, increasing cell density in a trabecular meshwork of an eye, increasing outflow of aqueous humor from an eye, or treating or preventing a medical condition in a subject.
