Expression Pattern :

Pattern  mir-84::gfp was first observed in the somatic gonad in larval stage 1 (L1). In L3 animals, strong expression was observed in uterine cells including the anchor cell (AC), and weak dynamic expression was observed in the vulval precursor cells (VPCs). mir-84::gfp expression was observed during the early to mid L3 stage in all the VPCs except for P6.p, in which expression was rarely observed. Subsequent VPC expression in the mid to late L3 stage was restricted to the daughters (Pn.px) of P5.p and P7.p with weaker GFP first appearing in the P6.p daughters just before their division into P6.pxx. Thereafter, equivalent expression was observed in the granddaughters (Pn.pxx) of P5.p, P6.p, and P7.p. In the L4 stage, GFP expression was maintained in the AC and other uterine cells, appeared weakly in hypodermal seam cells, and was upregulated to higher levels in many P5.p to P7.p descendants. Primary Identifier  Expr3472
Remark  mir-84::gfp expression was observed in all the VPCs except for P6.p at the stage when their fate in vulval development is determined by signaling from the AC, suggesting that mir-84 could play a role in vulval cell fate determination. A second let-7 family member, mir-48, was also expressed in non-P6.p VPCs, suggesting the potential for redundancy between mir-48 and mir-84 in the VPCs.
