gcm34 homozygous clones within mosaic spermathecae contain lumen epithelial cells, but completely lack secretory cells.
The INKA cell (a peptidergic, non-neuronal cell) can not be detected in most peritracheal cell clusters in homozygous embryos, whereas the other peritracheal cells remain detectable.
The INKA cell (a peptidergic, non-neuronal cell) can not be detected in most peritracheal cell clusters in gcm34/Df(2L)132 embryos, and in some cases other peritracheal cells in the cluster can not be detected.
In gcmN7-4/gcm34 embryos many glioblasts are transformed into neuroblasts.
gcmN7-4/gcm34 embryos have fewer hemocytes than normal, and the hemocytes show little migration compared to wild-type.
Homozygous embryos exhibit a drastic reduction in the number of glial cells. Studies of homozygotes and transheterozygotes with gcmN7-4 demonstrate most or all glial cells are transformed into neurons. Longitudinal fibres are partially or completely interrupted in several segments and the peripheral nerves exhibit defects.
