Identify the regulatory roles of intestinal secretory cell lineages during gut inflammation
… thesis systematically investigates the roles of secretory intestinal epithelial cells, specifically tuft cells and enteroendocrine cells (EECs), in colonic inflammation, revealing novel cellular and molecular dynamics. The initial study utilized IEC-specific Hnrnp I knockout mice to demonstrate …

Chemical Ecology of Defense Compounds in Anasa Species (Heteroptera: Coreidae) and Volatile Attractants for Diabrotica Species (Coleoptera: Chrysomelidae) (Attractants, Glands, Corn Rootworms, Electron Microscopy, Squash Bug)
… Lateral glands from A. tristis consist of secretory cells and duct cells, surrounding the central lumen of a gland tubule. The secretory cell possesses an electron dense collecting area and a microvillar network that projects into the cytoplasm. The secretory cell has numerous mitochondria, …

Measurement and Analysis of Calcium-Dependent Exocytosis in Giant Excised Membrane Patches
… exocytosis was studied in both excised and whole-cell patch clamp with emphasis on the rat secretory cell line, RBL. Capacitance and amperometric recordings show that secretory granules (SGs) containing serotonin are mostly lost from excised patches. Small vesicles that are retained (non-SGs) do …

Cytoskeletal Development In The Epidermal Cells Of An Insect, Calpodes Ethlius Stoll (lepidoptera:hesperiidae)
… the shape changes of individual epidermal cells. I have found that removal of the basal lamina from the epidermis allows the shape and basal surfaces of these cells to be seen by scanning electron microscopy. In the 5th larval stage of Calpodes ethlius the cells extend basal processes or …

The origin and properties of pro-oncogenic fields in the intestinal epithelium
… epithelium is maintained by intestinal stem cells that replace each other stochastically over time. Stem cells that are excluded from the stem cell pool will differentiate into the absorptive or secretory cell lineages. However, intestinal cell-fate specification is not always restrictive and …

Notch activation and clone fate in intestinal homeostasis and inflammation
… Notch signals are important for determining cell fate between the absorptive and secretory lineage and regulating the proliferation of intestinal stem cells (ISCs). As a result, Notch is also an important pathway during disease such as inflammation and previous literature has reported …

Exploring the transcriptomic landscape of the Drosophila melanogaster embryonic salivary gland.
… fuse to form a Y-shaped organ. Salivary gland cells do not undergo cell death or division, instead only through changing their shape, size, and neighbours. The short time window of specification, small cell population, continual lineage of cells and the established spatial patterning of genes …

Analysis of Hepatocyte Secretion Pathways: A Case Study on Hepatic Apolipoproteins, Serum Albumin, and Hepatitis C Virus
<p>The hepatocyte is one of the major secretory cell types in the body. It fulfills many of the liver's essential functions in protein secretion, lipid storage and transport, and excretion. Some of these functions are carried out via polarized secretion of simple protein cargo, such as serum …

Clinical and Molecular Analyses of Intestinal Goblet Cell Acidomucins and Cysteine Metabolism
Goblet cells are key contributors to intestinal mucosal barrier function through their role in production of mucins and other important secretory products, which include trefoil factor 3 (TFF3) and resistin like molecule β (RETNLB). Goblet cell mucins show great structural heterogeneity but can be …

Stem and Progenitor Cells in Homeostatic Maintenance and Perturbation of the Pulmonary Epithelium
… airway epithelium to lung squamous cell carcinoma in situ are well documented. However, the contribution of mutated tissue stem or progenitor cells to this process are poorly understood at the level of clonal resolution. Secretory cells are known progenitor cells of the …
