Optic Nerve Head

Another amazing image sent to us by Gabriel Luna out of the Steve Fisher and Geoff Lewis’s retinal cell biology group at UC Santa Barbara Neuroscience Research Institute.  This image is of the optic nerve head of a normal mouse retina displaying the “glial tubes” formed by the astrocytic network (anti-GFAP; red).  Anti-GFP (green) and anti-Collagen IV (blue) which were used to determine numbers of astrocytes and relative locations in relation to blood vessels.
