Figure 3.

PSA-NCAM in the human adult trigeminal ganglion (A, B: case 5, C-F: case 10). A-C: immunostained perikarya and nerve fibres; in B, a tissue section immunostained for PSA-NCAM and co-stained with modified Mayer's hematoxylin is shown. Arrows in A and B point to PSA-NCAM immunostained neurons whose nucleus is clearly detectable. C, F: the immunolabelling appears localized to the satellite cells surrounding non immunoreactive neurons. D, E: pericellular varicose arborisations around non immunoreactive neurons. Scale bars: A-C = 50 μm; D = 25 μm; E, F = 20 μm.
