Extracellular matrix distribution in the retina and optic nerve.

<p>Distribution of laminin (A,B,C), collagen I (D,E,F), collagen IV (G,H,I) and fibronectin (J,K,L) in green; in the retina (A,D,G,J scale for all pictures in J) the arrowheads point to the inner limiting membrane while arrows point to outer limiting membrane. The optic nerve head (B, E, H, K scale for all pictures in K) and in the optic nerve (C,F,I,L, scale for all pictures in L). βIII-tubulin labelling in the retinal ganglion cell axons is depicted in red, and DAPI labelling to stain cell nuclei is in blue.
