Abstract:
Cells containing small dense granules were present in the meninges surrounding the human embryonic optic nerve from 8 weeks post-conception. Typical fluorescent granular perithelial cells (FGP) containing large dense granules were present in the meninges by 12 weeks post-conception and in the large perivascular space around large vessels within the optic nerve by 14-15 weeks post-conception. The time of appearance of these cells in the CNS seems to be related to the stage of vascularization rather than to the stage of CNS development.
