Glial cells in longitudinal sections of P30 rat optic nerves.
A. Double labeled with rabbit anti-rat NG2 (green) and mouse CC1 antibody (magenta) that recognizes oligodendrocytes.
B. Double labeled with rabbit anti-rat NG2 (green) and guinea pig anti-GLAST (magenta) antibodies. NG2 cells and GLAST+ astrocytes represent non-overlapping cell populations.
C. Double labeled with rabbit anti-GFAP (green) and guinea pig anti-GLAST antibodies (magenta). GLAST and GFAP immunoreactivity are colocalized.
Scale bars = 20 µm. A: acquired by wide field microscopy. B and C: stacks of confocal images.
