Abstract
We studied the presence of β-nerve growth factor (NGF) mRNA in the submandibular gland of the mouse by in situ hybridization using 35S-labeled prepro-β-NGF antisense RNA. Female and male mice were studied at different stages of postnatal development, ranging from 3 to 12 weeks. Although NGF mRNA was detectable in the granular convoluted tubules of the submandibular gland in all the age and sex groups studied, the abundance of the signal dramatically increased after 5 weeks during the development of the submandibular gland. In addition, a conspicuous sexual dimorphism became increasingly apparent in the 6-, 7-, 10-, and 12-week-old animals, due to the remarkable development of the granular convoluted tubules in the adult male mouse, that expressed abundant NGF mRNA.
