Figure 3.

Figure 3

The expression of RALDH-2 and RALDH-3 is mutually exclusive. A: RALDH-2 is expressed by cells in the deeper aspects of the normal dorsomedial mucosa. B: RALDH-3 is completely absent from this region. C: Merged image of staining for both. D: In the ventrolateral mucosa RALDH-2 is expressed throughout the depth of the mucosa but less prominent in the regions directly subjacent to the basement membrane. E: RALDH-3 is confined to the cell layer directly subjacent to the basal lamina (arrowheads) and, additionally, to the periosteum at the deeper edge of the tissue. F: RALDH-2 and RALDH-3 are not expressed by the same cells in the unlesioned mucosa. In these images, arrowheads mark the basal lamina.
