Expression Pattern :

Pattern  Transgenic animals carrying these reporters displayed identical GFP signals in their hypodermis, structural cells, vulva, PQR, body seams and several neuronal processes in the head region at different developmental stages. The onset of mab-7::gfp expression was first detected in the hypodermis at the 2-fold stage. This hypodermal signal stayed on throughout the larval stages until the animals entered their adulthood. However, GFP expression in the body seam appeared only after the L4 stage and was maintained in adults. In the male tail, a GFP signal was detected at the late L4 stage in the structural cells when the ray retraction process was almost complete but prior to molting. This structural cell expression was also maintained in adults. Primary Identifier  Expr7804
Remark  Picture: Fig 3D to 3R. To define the specific cellular requirement, the onset of mab-7 expression in these cells was correlated with the first appearance of ray swelling in mab-7 mutant males. Ray abnormality first appeared when ray retraction started, which was well before mab-7::gfp expression in the structural cells was detectable prior to the final molting. The hypodermal expression profile of mab-7 at the late L4 stage, however, matched perfectly with the timing of this ray morphogenesis.
