The epithelial cells in the female reproductive tract play many important roles, including secreting hormones and growth factors. You can find epithelia, the plural for epithelium tissue, in a woman's ovaries, uterus and oviduct. The cells can secrete different hormones, cytokines and other substances that influence reproduction and health.
The air-blood barrier is mainly formed by two epithelial cell types: alveolar type I (ATI) and alveolar type II (ATII) cells. Whereas the cuboidal ATII cells produce surfactant and serve as progenitor cells for ATI cells, the latter themselves are more flattened and responsible for the gas exchange (Williams, 2003).
Personally everyone left right and centre does stem cells so I suggest moving away and being the shepherd but if it really is what floats your boat it really is up to you. Personally if stem cells is what you want to do start by: 1) Reading the wiki on Stem cells. Just a general overview so you know you're interested in it and it'll give it in a way you can comprehend. 2) Do the same around.
Amniotic epithelial cells (AECs) are a highly multipotent epithelial cell population isolated from the amnion. They develop from the epiblast 8 days after fertilization and before gastrulation. Owing to this timing of development, amnion epithelial cells maintain the plasticity of pregastrulation embryonic cells.
Epithelial cells are packed closely together in one or more layers. Epithelial tissue specialises in covering the body’s external and internal surfaces. The epithelial tissue located in the body’s interior is known as endothelium. Epithelial tissue can be split into two groups depending on the number of layers it’s composed of. When the epithelial tissue is only one cell thick it’s.Learn More
All glands are made up of epithelial cells. Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.Learn More
Abstract. Cell type- and locus-specificities of mutation induction were investigated in human mammary epithelial cells (HMEC). Primary cultures of normal and carcinoma HMEC, and immortalized nontumorigenic HMEC were exposed to ultraviolet (UV) radiation at the same dose and survival levels that have been reported to induce mutations in human diploid fibroblasts.Learn More
Dysfunction is commonly observed in inflammatory diseases and infection where the epithelial barrier is breached, and in ischemic states and invasive cancers, where malignant cells undergo epithelial to mesenchymal transition. Thus, it is important to identify molecules that mediate these processes in polarized epithelia.Learn More
Even with the epithelial cell layer intact, the virus is still able to enter into epithelial cells and can be trancytosed to regions where it can come in contact with a susceptible host(12, 16). A process called transcytosis is thought to be one of the major mechanisms involved in HIV-1 translocation across the single layer columnar epithelium found in the vaginal endocervix, colon and rectum.Learn More
My dissertation aims to further characterize the contribution of integrin signaling to epithelial polarity, particularly in the context of colorectal cancer (CRC). Therefore, this introductory chapter will provide a background discussion of several areas relevant to my work. Specifically, this chapter will cover key aspects of cell polarity, integrin biology, and receptor tyrosine kinase.Learn More
Retinal pigment epithelial (RPE) cells, a single layer of cuboidal epithelium located at the back of eye behind neural retina, gain access and proliferate in the vitreous during PVR. RPE cells in the vitreous undergo epithelial-mesenchymal transformation (EMT) and participate in the formation of contractile epiretinal membrane.Learn More
Degeneration and cell death of retinal pigment epithelial (RPE) cells, i.e. the cells that are the caretakers of photoreceptor cells, trigger secondary adverse effects in the neural retina leading to loss of vision. Currently, chronic oxidative stress and.Learn More
Together, the results in this dissertation led to a working model of collective cell migration as regulated by cell-matrix mechanical properties and cell-cell mechanical interactions. This model, as well as the quantitative techniques developed here, will drive future studies on the mechanisms underlying collective migration.Learn More
In summary, the endodermal epithelial cells are responsible for the absorptive and immune functions of the chicken yolk sac. The yolk sac mesoderm is critical for embryonic hematopoiesis and innate immunity. The chicken small intestinal epithelial cells are derived from the intestinal stem cells in the crypts.Learn More
Epithelial cells acquire mesenchymal characteristics by undergoing phenotypic and genotypic changes during cancer progression. An early step in the epithelial to mesenchymal transition (EMT) is the disruption of intercellular connections due to loss of epithelial cadherins.Learn More
This thesis addressed the potential role of these cellular interactions in differentiation and tumor progression of human mammary epithelium using a three-dimensional (3D) cell culture. Early development of breast cancer is characterized by the presence of few neoplastic epithelial cells amidst an excess of normal epithelial structures.Learn More
