Fig. 1. Ntn1a, ntn1b, dcc, and unc5b expression in the developing olfactory system. A subset of OSNs is labelled by expression of the Tg(or111-7:IRES:Gal4) transgene (green). (A) Frontal view max projection of the olfactory system of a 48 hpf larvae showing representative ntn1a expression (cyan) in the medial OB. The right olfactory epithelium (OE), olfactory bulb (OB), olfactory nerve (ON), and Central Zone protoglomerulus (CZ) are labeled. (B) Frontal view max projection of the olfactory system of a 48 hpf larvae showing representative ntn1b expression (magenta) ventral-medial to the CZ anteriorly, dorsal-lateral to the CZ posteriorly, and in the dorsolateral OB. The right olfactory epithelium (OE), olfactory bulb (OB), olfactory nerve (ON), and Central Zone protoglomerulus (CZ) are labeled. (C) Optical slice of a 36 hpf OE showing expression of dcc in an Tg(or111-7:IRES:Gal4);UAS:Citrine expressing OSN (White arrowhead). D. Optical slice of a 36 hpf OE showing expression of unc5b in an Tg(or111-7:IRES:Gal4);UAS:Citrine expressing OSN (White arrowhead).
