Figure 10.

The distribution of OSNs labeled with OR14 riboprobe is restored 3 months after unilateral MeBr lesion (AD-16), as shown by both the full-length OR14 riboprobe (A) and another one derived from the 3′UTR of the OR14 message (B). Both probes produce the same pattern of labeling on both sides. Lesioned indicates the open-naris side. Unlesioned indicates the closed-naris side. Counts indicate that slightly fewer OSNs are labeled by the 3′UTR probe; however, the boundaries of the OR14 territory (arrows) are situated in the same locations on both sides with both probes, suggesting that OSNs labeled by cross-hybridization to a closely related but distinct OR share the same territory, which is restored after the epithelium recovers from injury.
