TNF is a pleiotropic cytokine that modulates cell proliferation and apoptosis. The objective of the present study was to investigate the possible function(s) of the TNF/TNF‐R1 signaling pathway in embryonic mouse submandibular salivary gland (SMG) morphogenesis. After characterizing in vivo mRNA and protein expression of various constituents of this pathway, we utilized in vitro experiments to investigate the phenotypic outcomes of enhanced and deficient ligand. The results of these experiments indicate that the TNF/TNF‐R1 signal transduction pathway plays an important role in balancing cell proliferation and apoptosis during SMG duct and presumptive acini formation.
