WormMine: ExpressionPattern Expr12248

• Pattern: let-7 promoter directed temporal gfp expression in the seam cells of transgenic animals at the early L4 stage and in the adult. let-7 was observed in the anchor cell at L3 and in the distal tip cells at the adult stage. lin-4 and let-7 were weakly expressed in the anchor cell, which is required for proper vulval patterning, and in the P5.p, P6.p, and P7.p cells that will later differentiate into the mature vulva.
