摘要:: In this study, antiserum to acinar cell-specific mucin was utilized to determine whether mucin could be detected in the mouse submandibular gland prior to cytodifferentiation of acinar cells. Results from radioimmunoassay indicated that mucin occurs in submandibular glands from newborn mice, i.e., before the appearance of mature acinar cells. Additionally, mucin quantitated in various stages of development was found to be antigenically identical to adult mucin. After sections of glands were treated with immunohistochemical reagents, we observed that the mature acinar cell-specific mucin was present in secretory terminal-tubule cells and in proacinar cells of newborn animals. The present findings suggest that in young animals, the proacinar cells are an immediate precursor of acinar cells and that the secretory terminal-tubule cells may represent an earlier stage in development of acinar cells. In adult female glands, mucin was also detected in the granular intercalating-duct cells. This latter observation is consistent with the hypothesis that these cells are an intermediate in the acinar cell replacement process.
