Fig. 1. Isolation of identified ciliary cells from Helisoma trivolvis embryos. Schematic of a side view of a stage E30 Helisoma trivolvis embryo reveals the location of the various ciliary cells and embryonic neuron C1 (ENC1). A suction pipette was used to remove identified pieces of tissue from the surface of the embryo. DLB, dorsolateral ciliary band; PB, pedal ciliary band; SSC, scattered single ciliary cell.
