Effect of HDAC Inhibitors on Corneal Keratocyte Mechanical Phenotypes in 3-D Collagen Matrices
PURPOSE Histone deacetylase inhibitors (HDAC) have been shown to inhibit the TGFβ-induced myofibroblast transformation of corneal fibroblasts in 2-D culture. However, the effect of HDAC inhibitors on keratocyte spreading, contraction, and matrix remodeling in 3-D culture has not been directly assessed. The goal of this study was to investigate the effects of the HDAC inhibitors Trichostatin A (...
متن کاملGrowth factor regulation of corneal keratocyte differentiation and migration in compressed collagen matrices.
PURPOSE To evaluate a novel 3D culture model of the corneal stroma and apply it to investigate how key wound-healing growth factors regulate the mechanics of corneal keratocyte migration. METHODS Rabbit corneal keratocytes were seeded within collagen matrices that were compacted using external compression. Six-millimeter-diameter buttons were then incubated in media supplemented with 10% FBS,...
متن کاملTwist2: role in corneal stromal keratocyte proliferation and corneal thickness.
PURPOSE Twist2 is a member of a family of bHLH transcription factors critical for normal mesenchymal proliferation and differentiation. In this study, the authors analyzed the role of Twist2 in the eye and cornea through examination of a Twist2 loss-of-function mouse mutant. METHODS Twist2 expression during eye development in the mouse was investigated using RT-PCR and mRNA slide in situ hybr...
متن کاملContact dynamics during keratocyte motility
BACKGROUND Keratocytes are specialised, rapidly moving cells that generate substantial contractile force perpendicular to their direction of locomotion. Potential roles for contractile force in cell motility include cell-body transport, regulation of adhesion, and retraction of the cell's trailing edge. RESULTS To investigate contact dynamics, we used simultaneous confocal fluorescence and in...
متن کاملKeratocyte apoptosis after corneal surgery.
PURPOSE Programmed cell death (apoptosis) is the controlled death of cells that occurs with minimal collateral damage to surrounding cells or tissue during development, homeostasis, and wound healing. The authors hypothesize the keratocyte apoptosis is an initiating factor in the wound-healing response after refractive surgical procedures. To evaluate the effects of different corneal manipulati...
