WormMine: ExpressionPattern Expr13305

• Pattern: Using a microfluidic device, we obtained time-lapse data on the Y cell/PDA neuron transition, starting from the onset of Y cell migration in L1 to the expression of the exp-1 gene in the PDA neuron, as assessed by a transcriptional reporter (>30 hr, n = 25). During the imaging, animals molted three times to reach the L4 stage. When aligned for the L1 molt, reporter expression dynamics were largely synchronous between animals, with detectable expression beginning 5 hr after the L1 molt, reaching saturation around the end of the L3 stage.
