Dr. Vranka's project studied Versican, a large proteoglycan that is known to interact with many other proteins also present
in the trabecular meshwork, which is thought to be the primary contributor to outflow resistance.
Dr. Keller was awarded the 2010 Shaffer Prize for Innovative Glaucoma Research for her research investigating the role of Glycosaminoglycans (GAGs) in fluid outflow resistance
in the trabecular meshwork of the eye.

Its impact appears to reduce the ability of the cells
in the eye's
trabecular meshwork to continually move the clear aqueous humor out of the front of the eye and dump it into the body's general circulation, said Liu, corresponding author of the study
in the journal Investigative Ophthalmology & Visual Science.
Other data obtained
in this report (BrdU nitroblue tetrazolium staining by alkaline phosphatase and fluorescence due to fluorescein) would further suggest that putative stem cells are located
in the posterior limbus between the peripheral endothelium and the
trabecular meshwork.
The area of the
trabecular meshwork and its surrounding posterior limbus
in the human, however, showed considerable fluorescence indicative of cell division (Figure 6B).
Conclusions: It is suggested stem - like cells may be sequestered
in a niche at the junctional region where the corneal endothelial cells and the
trabecular meshwork come together.
No activity was observed
in the central endothelial tissues or the limbus between the
trabecular meshwork and Schwalbe's line.
In this report, no telomerase activity in the limbal region from Schwalbe's line to the trabecular meshwork was detecte
In this report, no telomerase activity
in the limbal region from Schwalbe's line to the trabecular meshwork was detecte
in the limbal region from Schwalbe's line to the
trabecular meshwork was detected.
There was also increased fluorescence
in the area of the
trabecular meshwork and posterior limbus of greater magnitude than
in the unwounded condition (Figure 7B).
However, we have found a fluorescent marker for nestin, a neural crest stem cell marker,
in the posterior limbal region of the human anterior segment
in the vicinity of both the
trabecular meshwork and Schwalbe's line (unpublished).
When BrdU fluorescence assays were made on corneal transverse sections with fluorescein, fluorescence occurred
in an area just at and adjacent to the
trabecular meshwork, but was not seen at the corneal endothelium.
By way of contrast, considerable fluorescence was observed
in the area of the
trabecular meshwork and the posterior limbus (Figure 6B).
The authors say that it's possible that the new
trabecular meshwork cells generated from the stem cell treatment could eventually succumb to the same mechanisms that caused the fluid buildup
in the first place, but further research is needed
in that area.

In most instances, OH results from impaired drainage of aqueous humor through the
trabecular meshwork ™.
TGF - Î ² 2 is known to elevate IOP by promoting increases
in aqueous humor outflow resistance through the
trabecular meshwork.

Our lab has recently shown that endogenous TGF - Î ² 2 expression can be markedly and significantly attenuated
in human
trabecular meshwork cells and porcine anterior segments using the compound XJB -5-131, a novel antioxidant that targets a cell's mitochondria.
RPB investigators have found that the normally spongy cells of the
trabecular meshwork (TM) might be hardened by calcification
in the eyes of people with glaucoma.
