Markers of embryonic stage 16 glial cells
Combinatorial codes of marker gene expression (at stage 16) in abdominal glial cells
(A2–A6) as related to cell types and their origin. Cluster analysis reveals degrees of
similarities or dissimilarities (as indicated by the order of branches) among the indivdidual glial cells (listed on top) in the combinations of genes expressed (listed on left
side). Similar expression codes become obvious for cells within, as well as significant
differences between the categories of surface- associated (SPGs, CGs: yellow),
cortex-associated (CBGs: green), and longitudinal glia (LGs: blue). Expression
patterns among the three nerve root glial cells (L-SNG, L-ISNG, M-ISNG) are significantly different from each other. The progenitors of the individual glial cells are indicated as superscripts. *mark stainings by in situ hybidization. Further genes found to be
expressed in glia at earlier stages (e.g. deadpan, gsb, hb, ldb, pdm, vnd) are not
incorporated.
Taken from:
Subtypes of glial cells in the Drosophila embryonic ventral nerve cord as related to lineage and gene expression.
