WormMine: ExpressionPattern Expr1389

• Pattern: The pattern of expression in larvae and adults was identical whether assayed by antibody staining or reporter gene. CeMyoD is expressed only in body wall muscle cells. CeMyoD antibody stained in the nuclei of very early embryonic blastomeres at about 120 min postfertilization. Staining initially is seen only in the two daughter cells of the D blastomere. Shortly after, CeMyoD is observed in the two daughters of both C.ap and C.pp. Staining is not seen in any of the embryonic blastomeres that produce other types of tissues, including pharyngeal muscle.
• Primary Identifier: Expr1389
• Remark: hlh-1 is called CeMyoD in the article.
• Subcellular Localization: Nuclear staining with the CeMyoD antibody is observed in all descendants of the immunopositive early blastomeres as they continue to divide and ultimately differentiate into body wall muscles.
