| Term |
adult lamina marginal glial cell |
ID (Ontology) |
FBbt:00005722 (Fly Anatomy) |
| Definition |
Specialized ensheathing glial cell of the lamina (Edwards et al., 2012; Kremer et al., 2017). These cells form a contiguous layer at the proximal surface of the lamina and associate with multiple lamina columns (Edwards et al., 2012; Kremer et al., 2017). Their processes extend into the lamina, ensheathing proximal parts of the cartridges (Kremer et al., 2017). They also extend protrusions proximally into the outer chiasm (Kremer et al., 2017). It is between the marginal glial cells and epithelial glial cells that the R1-R6 growth cones terminate (Poeck et al., 2001; Winberg et al., 1992). There are around 100 of these cells per lamina (Kremer et al., 2017).[ FlyBase:FBrf0055906 FlyBase:FBrf0134808 FlyBase:FBrf0205531 FlyBase:FBrf0218414 FlyBase:FBrf0234767 ] |
