Fig. 7. Expression of Xenopus V2Rs in the olfactory and vomeronasal
epithelial cells of Xenopus larvae. Cross sections of Xenopus
larvae at stage 45 (A) and stage 50 (B–D) were hybridized to
digoxigenin-labeled antisense probes prepared from clones E-1
(A,B,D) and xV2R1 (C). Arrows indicate the receptor-expressing cells.
OE, olfactory epithelium; VNO, vomeronasal organ. Scale bars 50

Fig. 3. Analysis of Xenopus V2R expression in the vomeronasal
organs by in situ hybridization. Cross sections of Xenopus vomeronasal
epithelium were stained with hematoxylin (A). The cross
sections were hybridized to digoxigenin-labeled antisense
probes which were derived from clones A-1 (B), B-1 (C), C-1 (D),
E-1 (E), xV2R1 (F), a mixture of A-1, C-1, and E-1 (G), and sense
probes derived from a mixture of A-1, C-1, and E-1 (H). RE, receptor
cell layer; SU, supporting cell layer; VL, lumen of the VNO. Black
spots around the outside of the VNO in A–H (for example, arrow
in F) are melanocyte aggregates. Scale bars 50 m. |
