Fig. 5. Expression pattern of sdf-9. (A) Expression of sdf-9p::GFP2 (pKOG9) in the head region of an L3 larva. The left-hand cell, which is in focus in this micrograph, is strongly fluorescent, while the right-hand cell, which is also strongly fluorescent, is out of focus. The arrows indicate short dendrite-like structures. (B) Expression of sdf-9p::GFP2 expression in the head region of an L1 larva. The right-hand cell that express the GFP fusion gene is indicated. The arrow shows the dendrite-like process, which extends to the tip of the head. (C) Expression of SDF-9::GFP (pKOG7) in two head cells of a daf-9(e1406) dauer larva. One of the two dendrite-like processes extends posteriorly. Both cells have processes, but those of the left-hand cell are out of focus. The images in the right white boxes in (A) and (B) are magnified versions of those in the left white boxes, respectively, and the bottom image is a magnified version of that in the white box in (C). Scale bar: 10 µm.
