Primary Porcine Trabecular Meshwork
This winning image from GE Healthcare’s IN Cell Image Competition of 2008/9 reveals the internal structure of a fluorescently-stained trabecular meshwork cell. The red linear structures are filaments of actin spread throughout the cell, while the green patches at their tips are focal adhesions. DNA has been stained in blue.
The trabecular meshwork is located around the base of the cornea, near the ciliary body, and functions to drain aqueous humor from the eye. Excessive aqueous humor production or reduction to the outflow of aqueous humor can lead to an increase in intraocular pressure, which is normally associated with glaucoma.
