WormMine: ExpressionPattern Expr542

• Pattern: Expressed in hypodermal precursors, primordial pharynx, and cells surrounding developing buccal and rectal openings at comma stage embryo. Found in P1/2 - P11/12, V1L/R - V6L/R, H0L/R - H2L/R, hyp4, hyp6, and hyp7 cells at comma to 1.5-fold stage embryo. First detected at ~500-cell stage in hypodermal precursor cells and several unidentified cells in the developing tail. Comma-stage and 1.5-fold stage, Expression in many hypodermal precursor cells including P1-12, V1-6 (QV5), H0-H2, hyp4, hyp6, hyp7 cells as well as several presumptive hypodermal cells clustered in the tail. Expression at this stage is also observed in the primordial pharynx as well as in the arcade cells encircling the forming buccal cavity. Posterior expression is detected in cells surrounding the forming rectum and in other cells likely to be neuronal precursors. Later in embryogenesis, GFP detected in majority of pharyngeal cells as well as in neurons with no difference in expression in the cells of the hypodermis. In larvae, GFP observed predominantly in neurons. Staining in ventral nerve cord (first detected in L1 prior to migration of P-cells and is later observed in many cells of the ventral nerve cord from L2-L4). Staining is also detected in hermaphrodite-specific neurons HSN beginning around L2 stage and in the canal associated neurons beginning around L3. Staining is also seen in many neurons of the anterior nerve ring, the dorsal nerve cord and several neurons in the tail. In young adult, weak expression observed in muscle cells.
