hlh-3 expression. (A) Illustration of image B, indicating body position of GFP-positive P cells as circles. (B)
hlh-3 is expressed in the ectodermal-like P cells. Wa and Wp are daughter cells of W, a cell with a lineage similar to the P cells. (C) P cell daughters express
hlh-3. Anterior daughters, such as P5a and P9a, are primary neural precursors (neuroblasts). Posterior daughters, such as P5p and P9p, are hypodermal blast cells. P2aa and P2ap are secondary neural precursors. Note that
hlh-3 expression appears to fade in hypodermal cells such as P2p. (D) Expression of
hlh-3 in secondary neural precursors. (E)
hlh-3 expression in ventral nerve cord (VNC) motor neurons derived from the P cell lineages. (F) Illustration of image H, indicating body position of the HSN and VC motor neurons. (G) GFP-positive neurons in the head region boxed in F. Circles indicate position of pharyngeal bulbs. (H) Expression of
hlh-3 in the HSNs and VCs at the third larval stage (L3). Open arrow indicates out-of-frame position of HSNR. (A-H) All images anterior to the left, ventral down.
