Phenotype of the compound transgenic fish of Tg [en1b:loxP-RFP-loxP-DTA] and Tg[hoxa9a-3'enhancer:Cre] (related to Figures 2 and 3) a, Fluorescent images of Tg[en1b:loxP-RFP-loxP-DTA] fish without a Cre driver (top panel), with Tg [hoxa9a-3'enhancer:Cre] (middle panel), and Tg[hoxa4a/9a:Cre] (bottom panel). Arrowheads indicate the boundary between the hindbrain and the spinal cord. Scale bar, 250 μm. b, VR and slow-type MN recordings during fictive swimming elicited by electrical stimulation in a control (top panel) and a compound transgenic fish of Tg[en1b:loxP-RFP-loxP-DTA] and Tg[hoxa9a-3'enhancer:Cre] (bottom panel).
