a, b SMG-B immunohistochemistry of 5 & 7 days and 8 weeks deligated submandibular glands respectively. In both the 5 & 7 day deligated glands SMG-B exclusively localized in the acinar cell (arrows) whilst the duct are negative. The acini at the end of the branched structures are also positive (double arrows inset). c AB/PAS staining of 8 weeks deligated glands showing recovery of the secretory granules in the acini and in the granular duct cells (arrow). d SMG-B immunohistochemistry 8 weeks deligated submandibular glands; most of the acini are now negative, except for few occasional cells (arrow). The intercalated ducts cells do not show immunoreactivity (arrowhead). All sections were counterstained with haematoxylin. The occasional nuclear staining is an artefact due to antigen retrieval pre-treatment.
