Progenitor-progeny relationships in airway epithelium.
Scott H. Randell, Ph.D. M any disease processes in airways are characterized by altered epithehial cell phenotype. The spectrum ranges from loss of cilia through mucous cell hypertrophy, hyperplasia, and squamous metaplasia to neoplasia. A useful step toward understanding the regulation of airway cell proliferation and differentiation is elucidation of progenitorprogeny relationships. The curre...
متن کاملA tumor promoter-resistant subpopulation of progenitor cells is larger in limbal epithelium than in corneal epithelium.
PURPOSE In the epidermis, proliferative basal cells can be divided into two subpopulations according to their response to phorbol ester tumor promoters. The tumor promoter-sensitive subpopulation ceases mitosis and initiates terminal differentiation and, thus, represents more differentiated transient amplifying cells. In contrast, the tumor promoter-resistant subpopulation that continues to pro...
متن کاملA comparison of stem cell-related gene expression in the progenitor-rich limbal epithelium and the differentiating central corneal epithelium
PURPOSE Corneal epithelium is maintained by a population of stem cells (SCs) that have not been identified by specific molecular markers. The objective of this study was to find new putative markers for these SCs and to identify associated molecular pathways. METHODS Real time PCR (rt-PCR) was performed in 24 human limbal and central corneal epithelial samples to evaluate the gene expression ...
متن کاملTissue engineering and the use of stem/progenitor cells for airway epithelium repair.
Stem/progenitor cells can be used to repair defects in the airway wall, resulting from e.g., tumors, trauma, tissue reactions following long-time intubations, or diseases that are associated with epithelial damage. Several potential sources of cells for airway epithelium have been identified. These can be divided into two groups. The first group consists of endogenous progenitor cells present i...
متن کاملCharacterization of dental epithelial progenitor cells derived from cervical-loop epithelium in a rat lower incisor.
Dental epithelial progenitor cells differentiate into various cell types during development of tooth germs. To study this mechanism, we produced immortalized dental epithelial progenitor cells derived from the cervical-loop epithelium of a rat lower incisor. The expression patterns of cytokeratin 14, nerve growth factor receptor p75, amelogenin, Notch2, and alkaline phosphatase were examined by...
