Murine trabecular meshwork cells in tissue culture.

Abstract:

:Trabecular meshwork cells from an inbred strain of mice (A/J) were established in tissue culture. Within 1 hour of enucleation, tissue containing the cornea and the chamber angle was excised and placed in tissue culture. Two to five days later, three cell types grew from the explants. Two of these cell types, corneal endothelium and fibroblasts, grew together, with the fibroblasts preferentially spreading on top of the endothelial cells. The trabecular meshwork cells extended from the explant as a distinct morphological type. The corneal endothelium and its associated fibroblasts were then removed from the culture flask with a sterile cotton swab, leaving a monolayer of pure trabecular meshwork cells. These cells required 3-4 weeks to reach confluency and could be passaged five times. They were actively phagocytic in culture and exhibited immunoreactivity to antibodies against two extracellular matrix components, laminin and collagen type IV. Mouse trabecular meshwork cells also expressed receptors for acetylated low-density lipoprotein, a property shared by trabecular meshwork cells derived from other species. The availability of trabecular meshwork cells from an inbred strain of mice will facilitate future in vivo functional studies of these cells in a syngeneic system, as well as investigations of potential immunoregulatory properties of the trabecular meshwork.
