The larvae were treated with 200 µM neomycin to deplete the hair cells in neuromast and ampullary organ. Two kinds of sensory epithelia at the ventral side of head were separated at 12 hour-post treatment (hpt) and 24 hpt, respectively. Mechano- and electro- sensory epithelia before neomycin treating were collected respectively as control (untreated).The epithelia near but without two kinds of sensors (EPs) were also collected. Total RNAs were extracted by TRIzol (Invitrogen) using standard protocols. RNA libraries were prepared by TruSeq RNA Sample Prep Kit (Illumina), following the manufacturer's instructions. Overall design: 14 samples
