embryonic/larval peritracheal cell

ID: FBbt_00006017

Cell located at the branch points of the embryonic or larval trachea. It is part of a bilaterally-symmetrical, segmentally-repeated cluster of three cells that are connected by cytoplasmic processes (Laneve et al., 2013. These clusters are found in six abdominal segments, one to three thoracic segments and the head region (Laneve et al., 2013. One cell per cluster is a non-neuronal peptidergic cell (PM cell), which shows a complex morphology and extends several cytoplasmic processes. The PM cell is located on the main dorsal trunk trachea and the non-peptidergic cells (PMa cells) are located on the transverse tracheal connective (O'Brien and Taghert, 1998; Laneve et al., 2013. (Hewes et al., 2003, O'Brien and Taghert, 1998, Laneve et al., 2013, Hartenstein and Jan, 1992)

These three-cell clusters can be identified by expression of gcm (Laneve et al., 2013.
