  • Title: Immunocytochemical localization of epidermal growth factor during the postnatal development of the submandibular gland of the mouse.
    Author: Gresik EW, Barka T.
    Journal: Am J Anat; 1978 Jan; 151(1):1-9. PubMed ID: 341680.
    Abstract:
    The time of appearance and the pattern of localization of epidermal growth factor (EGF) in submandibular glands of mice was studied during postnatal development immunocytochemically. EGF was first detectable in the granular convoluted tubule (GCT) cells in the glands of males at 20 days of age and of females at 30 days of age. Development of GCT cells containing EGF was rapid in males, approaching adult conditions by 45 days of age. In females EGF- containing GCTs developed more slowly and irregularly, and did not reach adult status by 45 days of age. It is concluded that EGF is restricted during postnatal development to the GCT cells, and that these cells and the distribution of EGF are represented dimorphically from their first appearance in the submandibular glands of both sexes.
