WormMine: ExpressionPattern Expr2291

• Pattern: SQV-4 Abs stained the cytoplasm of many cells, including (but not limited to) oocytes and vulval cells, as well as uterine, seam, pharyngeal, and spermathecal cells. During the early L4 stage, 10 of the 22 vulval nuclei were in cells with dramatically increased expression of SQV-4. These 10 nuclei are the six inner nuclei of the P5.p and P7.p descendants and the four outer nuclei of the P6.p descendants. During the mid-late L4 stage and thereafter, cells containing the inner four nuclei of the P6.p descendants also increased SQV-4 expression, bringing the total of vulval nuclei that highly expressed SQV-4 to 14. Thus, the 22 vulval nuclei define three classes based on the levels and timing of SQV-4 expression.
