Additional Descriptive Data

sim is expressed in the ventral regions of the embryonic foregut and hindgut.

(Maeda et al., 2007)

Expression assayed at stages 9, 11, 13, and 17. Expression may be continuous between assayed stages in some tissues.

(Wheeler et al., 2006)

sim is first detected in the mesoderm at stage 11 in a cluster of 3-5 cells per hemisegment lying just adjacent to the ventral midline. In late stage 11, a more laterally place cluster is observed. Shortly after their appearance, sim-expressing mesodermal cells migrate laterally away from the midline towards the body wall. By the beginning of germ band retraction, the two cell clusters merge and form a single row of sim-positive cells on either side of the ventral midline. These cells elongate and begin to take on the morphology of muscle syncytia. sim expression begins to fade shortly after muscle cell fusion. Weak staining can be detected later in a subset of ventral oblique muscles.

(Lewis and Crews, 1994)

sim protein is first observed at the end of gastrulation in a strip of cells along the ventral midline. The sim-positive cells extend up into the presumptive head region where they form an annulus around the presumptive anterior midgut invagination. By hour 5, the neuroblasts begin delaminating from the ectodermal epithelium. sim-positive cells delaminate to give rise to the midline cells of the CNS. sim protein is expressed in precursors of both neuronal and non-neuronal cells lying at the midline but is found at different level in different cells. By later stages, expression is low in the median neuroblast and in the VUM neurons and is high in the six midline glial cells.
