Histone deacetylase inhibitors blocked activation and caused senescence of corneal stromal cells.

ABSTRACT:

Purpose

Corneal myofibroblasts differentiated from activated corneal stromal cells are the major cellular sources of extracellular matrix synthesis for the repair of corneal injury. In this study, the effects of histone deacetylase (HDAC) inhibitors on the activation, proliferation, migration and senescence of corneal stromal cells were evaluated.

Methods

Primary human and mouse corneal stromal cells were harvested by sequential digestion with dispase and collagenase, and cultured in DMEM/F-12 media under serum-free (keratocytes), serum- (corneal fibroblasts) and TGFbeta1-supplemented (corneal myofibroblasts) conditions. The responses of corneal stromal cells to HDAC inhibitors were characterized by cDNA microarray, real time PCR, immunocytochemistry and western blot analysi
