Salivary Gland Stromal Heterogeneity And Epithelial Controls, Nicholas L. Moskwa
Salivary Gland Stromal Heterogeneity And Epithelial Controls, Nicholas L. Moskwa
Legacy Theses & Dissertations (2009 - 2024)
Organogenesis is the process organs go through where cellular communications coordinate all a developing organ needs. What organs need are more cells, in the right place, doing the right job. In the salivary gland, we know that stromal cells are important for organogenesis and that they coordinate the epithelium’s form and functions. However, specific stromal contributions have focused on epithelial quantity and placement. There is less information about how the stroma directs the epithelium towards certain functions. Here we used organoids as a model for understanding what stromal signaling directs epithelial cell fate. We found that stromal cell state is …
Myoepithelial Cell Morphogenesis And Differentiation In The Mouse Submandibular Salivary Gland In Development And Disease, Elise Marie Gervais
Myoepithelial Cell Morphogenesis And Differentiation In The Mouse Submandibular Salivary Gland In Development And Disease, Elise Marie Gervais
Legacy Theses & Dissertations (2009 - 2024)
Organogenesis is the process by which tissues organize, gain considerable size, and undergo cellular differentiation or specialization to form fully functional organs. To study the processes involved in organogenesis of branched organs, the mouse submandibular salivary gland is frequently used as a model system, as it can undergo morphogenesis and differentiation and be genetically manipulated ex vivo. The mouse submandibular salivary gland undergoes a specific process of outgrowth and invagination known as branching morphogenesis which allows for the significant increase in gland size and complexity, as well as maximization of surface area for secretion of saliva. Surrounding the mouse submandibular …
Using A Novel Multiplexing Method To Track Cell Populations And Cytodifferentiation During Development Of The Submandibular Salivary Gland, Charles Thomas Manhardt
Using A Novel Multiplexing Method To Track Cell Populations And Cytodifferentiation During Development Of The Submandibular Salivary Gland, Charles Thomas Manhardt
Legacy Theses & Dissertations (2009 - 2024)
The development of submandibular salivary glands is complex and requires coordination of specific signaling events. Submandibular salivary glands originate as an epithelial invagination into the adjacent mesenchyme that leads to a single stalk and end bud; this end bud will go through a clefting process. Numerous rounds of clefting will lead to a fully developed salivary gland by this process, which is known as branching morphogenesis. As the gland undergoes morphogenesis, specific cues leading to differentiation of multiple cell types and even epithelial sub classes are required. By the later stages of development the glands are fully innervated, have an …
Mouse Salivary Gland Development Requires Optimal Substrate Compliance, Sarah Beth Peters
Mouse Salivary Gland Development Requires Optimal Substrate Compliance, Sarah Beth Peters
Legacy Theses & Dissertations (2009 - 2024)
The embryonic mouse submandibular salivary gland (mSMG) is a classic model to study mechanochemical signals involved in morphogenesis and differentiation amongst multiple, interacting cell populations. Scaffold compliance is alters cellular phenotype, but little is known about the effects of compliance on organogenesis. The overall aim of this project was to demonstrate that the processes of salivary gland epithelial branching morphogenesis and differentiation require a compliant, in vivo-like environment and are disrupted outside of this range.
Computational Modeling-Driven Study Of Signaling Pathway Affecting Cleft Formation During Submandibular Salivary Gland Development, Shayoni Ray
Legacy Theses & Dissertations (2009 - 2024)
Branching morphogenesis is a conserved mechanism of mammalian organ development (salivary glands, lungs, mammary glands, pancreas, kidney, etc.), and has been a classic topic of study for generations of developmental biologists. During the process of tissue formation, several cellular and molecular and protein signaling events occur at successive stages enabling proper formation of tissue shape and structure. In order to provide a comprehensive understanding of the process of branching morphogenesis, we need a systems level approach to integrate multifactorial information. My overall global hypothesis is that multiple mathematical modeling approaches can be utilized to extract crucial cellular and tissue level …

The P38 Alpha Stress-Activated Protein Kinase Pathway In Mammary Gland Development And Cancer, Huei-Chi Wen
Legacy Theses & Dissertations (2009 - 2024)
Breast tumors arise from preinvasive lesions consisting of abnormal epithelial cells that accumulate within the mammary duct. However, the initiating steps and underlying pathways leading to the formation of these early stages of breast carcinoma, such as ductal carcinoma in situ (DCIS), is not fully understood.
Rho Kinase Regulates Basement Membrane Dynamics To Coordinate Salivary Gland Branching Morphogenesis And Tissue Organization, William Patrick Daley
Rho Kinase Regulates Basement Membrane Dynamics To Coordinate Salivary Gland Branching Morphogenesis And Tissue Organization, William Patrick Daley
Legacy Theses & Dissertations (2009 - 2024)
Branching morphogenesis is a developmental mechanism utilized by many organs, including the salivary gland, lung, kidney, and mammary gland, to increase the epithelial surface area for secretion or absorption. The embryonic submandibular salivary gland (SMG) is a classic model for studying tissue morphogenesis in three dimensions ex vivo. Salivary gland development requires distinct but overlapping processes: morphogenesis, the actual physical rearrangement of cells into complex three dimensional structures, and cytodifferentiation, the process by which these cells begin to take on their own specialized function. Polarization, or the organization of cells into a cohesive tissue structure, also occurs concurrently during organ …
