Trabecular Meshwork Stem Cells for Glaucoma Treatment.

Elevated intraocular pressure (IOP) is the most important risk factor for primary open-angle glaucoma (POAG) and currently is the only effective treatment target for glaucoma to prevent vision loss. In POAG patients, the trabecular meshwork (TM) cellularity is reduced which might be the main pathologic reason for the conventional outflow pathway dysfunction leading to elevated IOP. Stem cell-based therapy has been shown promising to reduce IOP and preserve retinal ganglion cells and their function in animal models. In this chapter, we describe the method details on TM stem cell cultivation and identification; induction for differentiation into different cell types, including differentiation to TM cell responsiveness to dexamethasone treatment with phagocytic function; and transplantation into mouse anterior chamber for therapeutic purposes.
