Distribution of β integrins and pY397 FAK in RGCs growing in laminin.

<p>Paired images A-B, C-D, and E-F of RGCs labelled with a βIII-tubulin antibody in red (A,C,E), and β1 (B) and β3 (D) integrins and pY397 FAK (F) in green. Note that the long RGC neurites pointed out with arrows in C and E are not labelled with either β3 or pY397 FAK while the rest of RGCs and their neurites expressed the integrins and were labelled for phosphorylated FAK. Scale bar for all pictures in F.
