Project description:We used embryonic day 15 submandibular salivary glands from K5-Venus mice, which were produced using the bovine-K5 promoter driving Venus expression, N=3 separate experiments
Project description:Gene expression profiling and sialadenitis scoring in submandibular salivary glands from mice congenic for the two chromosomal regions Nss1 and Idd5.
Project description:Sequencing of mRNA isolated from salivary glands of control mice and mice overexpressing RANKL in keratin 5 (K5)-positive cells for 2 weeks.
Project description:To reveal novel molecular factors behind the development of salivary gland cancer, we performed gene expression analyses from Smgb-Tag mouse salivary gland samples. The overall purpose was to apply these results for clinical use to find new approaches for both possible therapeutic targets and more accurate diagnostic tools in identification of salivary gland cancers. Smgb-Tag mouse strain, in which salivary neoplasms arise through a dysplastic phase in submandibular glands, was investigated using genome-wide microarray expression analysis, Ingenuity pathway analysis, RT-PCR, and immunohistochemistry. 3 normal, 3 dysplastic, and 3 adenocarcinomatous submandibular gland tumours of Smgb-Tag mice.
Project description:The aim of this study is characterize the gene expression of rat parotid, submandibular and sublingual glands, providing basic information for the salivary marker proteins.
Project description:Dysfunction of salivary glands is one of the common symptoms of diabetes. Although the long non-coding RNA has recently been identified to play a role in the pathogenesis of diabetes, it is still unclear about the role of lncRNA in diabetes salivary glands. This work was aimed to explore the lncRNA-miRNA-mRNA expression profiles and functional network in diabetes submandibular gland
Project description:Mus musculus embryonic submandibular salivary glands from embryonic day 12.5 embryos were laser microdissected to isolate epithelial cells from regions adjacent to forming clefts or from the peripheral end bud region. The isolated region-specific samples were then subjected to T7-SAGE transcriptome analysis. Toluidine blue-stained cryostat sections of embryonic day 12.5 submandibular salivary glands were used for laser microdissection using an LMD system (Leica) with a pulsed UV laser on an upright automated microscope. A total of approximately 500 cells from a region immediately adjacent to a forming cleft or from a peripheral end bud region were excised by the laser and transferred to caps of 0.5 ml PCR tubes. SAGE libraries were constructed from the microdissected cleft and bud epithelia cells. SAGE tags were identified using the National Center for Biotechnology Information (NCBI) tag map set for UniGene.
Project description:Our single-cell and bulk transcriptome analyses revealed striking molecular heterogeneity in the mesenchymal cells of embryonic submandibular and parotid salivary glands during bud initiation, including distinct mesodermal and neural crest-derived molecular signatures that foreshadow later functions.

Project description:Salivary glands that produce and secret saliva, which is essential for lubrication, digestion, immunity, and oral homeostasis, consist of diverse cells. Maintenance of diverse salivary gland cells in organoids remains problematic. Here, we established human salivary gland organoids, which is composed of multiple cellular subsets, from 3 major salivary glands, including parotid gland (PG), submandibular gland (SMG), and sublingual gland (SLG). Human salivary gland organoids expressed gland-specific genes and proteins of acinar, myoepithelial, and duct cells. Organoids were maintained in growth media (named GEM) and further underwent differentiation in differentiation media (named DAM). Our study will provide an experimental platform for the exploration of mechanisms involvled in tissue regeneration, development, or several salivary gland diseases.
