WormMine: ExpressionPattern Expr14286

• Pattern: We observed that phsp-4::GFP reporter was visibly induced in seam cells during two developmental stages -weakly in the late L4 stage and strongly in L2 stage animals on starved crowded plates- while it was undetectable in other larval stages. Closer examination suggested that hsp-4 expression is indeed induced in the posterior daughter cells, fated to differentiate into alae-secreting cells after the last asymmetric division.
