embryonic/larval peritracheal PM cell [FBbt_00047703]

Neuropeptide-secreting peritracheal cell. There is one of these cells among each cluster of embryonic/larval peritracheal cells and 14 in total per organism (Park et al., 2008; Laneve et al., 2013). It has a more complex morphology than the PMa cells, extending several cytoplasmic processes (Laneve et al., 2013). It is located on the main dorsal trunk trachea, adjacent to the branch point from which the transverse connective trachea splits off (O’Brien and Taghert, 1998; Laneve et al., 2013).

Cell Larva

Neuropeptide-secreting peritracheal cell. There is one of these cells among each cluster of embryonic/larval peritracheal cells and 14 in total per organism (Park et al., 2008; Laneve et al., 2013). It has a more complex morphology than the PMa cells, extending several cytoplasmic processes (Laneve et al., 2013). It is located on the main dorsal trunk trachea, adjacent to the branch point from which the transverse connective trachea splits off (O'Brien and Taghert, 1998; Laneve et al., 2013).

This cell stains with molluscan myomodulin antibody just before ecdysis and staining disappears at the time of ecdysis, indicating release of myomodulin-related peptides. In other insects, these cells release ecdysis triggering hormone (ETH), but this was not seen in Drosophila (O'Brien and Taghert, 1998). It expresses dimm and Phm, as is typical for peptidergic cells (Hewes et al., 2003). Additionally expresses gcm (Laneve et al., 2013).
