midline glial cell [FBbt_00001315]
Neuropil associated CNS glial cell located along the midline in the ventral nerve cord. There are three to four midline glia per neuromere, in the anterior region, arranged and above (dorsal to) and below (ventral to) the neuropil. These cells originate from a group of 7-8 cells at embryonic stage 13 which are reduced by apoptosis to 3-4 glial cells by embryonic stage 16. These glial cells ensheath the anterior and posterior axon commissures, with cytoplasmic extensions restricted to the midline, covering the medial part of the commissure neuropil. Fine extensions are also observed within the neuropil. Ito et al. (1995) states that there are generally three or four midline glial cells per neuromere, but occasionally there are more than four. The thoracic neuromeres are more likely than the abdominal neuromeres to have more. Midline glia are repo (FBgn0011701) negative and are eliminated by apoptosis during the pupal stage.
