title: Cell proliferation in the mouse parotid gland after unilateral parotidectomy.
abstract: Unilateral parotidectomy with or without total submandibulectomy has been used to induce cell proliferation in mouse parotid gland. Maximum DNA synthesis and mitosis were recorded four and five days after the operation. The double operation increased the proliferative response. Such proliferative stimulii was not accompanied by secretion and was sex independent. On the other hand, the response decreased with age. RNA and protein synthesis inhibitors showed that the stimulation of DNA synthesis depends on early protein synthesis, which seems to be synthesized on a preexisting template.
