Effect of cytoglobin overexpression on extracellular matrix component synthesis in human tenon fibroblasts

Biol. Res; 52 (), 2019
BACKGROUND: Conjunctival filtering bleb scar formation is the main reason for the failure of glaucoma filtration surgery. Cytoglobin (Cygb) has been reported to play an important role in extracellular matrix (ECM) remodeling, fibrosis and tissue damage repairing. This study aimed to investigate the role ...
