PSP mRNA expression level in the 2 weeks ligated (2 weeks lig.), 2 weeks ligated plus 3 or 5 or 7 days deligated (3 days reg.; 5 days reg.; 7 days reg.) using the unoperated adult submandibular glands as baseline. The 5 days deligated gland (5 days reg.) revealed an increase in SMG-B expression (p<0.05) compared to the 3 days deligated gland. The level of PSP did not increase further during the progression of the regeneration (day 7). The psp transcript was up-regulated at 5 and 7 days of regeneration compared to the normal gland (30 and 50 fold change respectively; ^*p<0.05).
