Well, gosh. There's no description for this book yet. Can you help?

Biomechanical testing of human trabecular meshwork cells and Schlemm's canal endothelial cells.

Published 2005 .
Written in English.

About the Book

Actin cytotoskeletal changes in trabecular meshwork (TM) cells and Schlemm's canal (SC) endothelial cells have been observed in glaucomatous eyes. It is believed that these changes may affect the biomechanical properties of the cells, and hence may impact their resistance to aqueous outflow. Increased resistance to flow elevates intraocular pressure, a major risk factor in glaucoma. In this thesis, we present the first measurements of biomechanical properties of cultured TM cells (average stiffness: 0.0161 +/- 0.0022 Pa-m; average viscosity: 0.0903 +/- 0.0148 Pa-m-s) and SC cells (average stiffness: 0.0184 +/- 0.0031 Pa-m; average viscosity. 0.0804 +/- 0.0111 Pa-m-s). Treatment of TM cells with the actin altering agent Latrunculin-B disrupted the actin cytoskeleton and decreased TM cell stiffness by 37%. Treatment with Dexamethasone induced cross-linked actin network formation but how this affected stiffness could not be determined. Actin plays a major role in determining cell stiffness but it is unclear how its organization affects cellular biomechanical properties.
