Figure 4.—

TRPV subunits that control egg-laying behavior are coexpressed only in uv1, the uterus-associated endocrine cells. (A–C) Expression patterns of GFP reporter constructs for TRPV subunits that control egg-laying behavior. Overlays of fluorescence and bright-field images of animals carrying GFP reporter transgenes for OCR-2 (A), OCR-4 (B), and OCR-1 (C). Bars, 30 μm. Fluorescent utse, uv1, and uv3 cells are labeled. Other cell bodies (brackets) and the vulva (*) are also indicated. Bottom right of A and B show expression in the two left uv1 cells, although the two right uv1 cells also expressed the reporter. For clarity, these and all subsequent confocal images of uv1 show only the left side.
