The appearance and distribution of microglia in the developing cerebellum has been
examined with the aid of a peroxidase-conjugated lectin derived from Griffonia simplicifolia.
This distribution has in turn been correlated with that of pyknotic figures in the same Nissl-
counterstained sections, in order to gain an understanding of the role of microglia in the
developing cerebellum. Round and ameboid microglia may be recognised in the fetal
cerebellum as early as E11. Numbers of microglia increase steadily from that time, with …
