Evolution of cooperation in an epithelium [PDF]

open access: yesJournal of The Royal Society Interface, 2019
Cooperation is prevalent in nature, not only in the context of social interactions within the animal kingdom but also on the cellular level. In cancer, for example, tumour cells can cooperate by producing growth factors. The evolution of cooperation has traditionally been studied for well-mixed populations under the framework of evolutionary game ...

Correlation of pericoronal radiographic width with histopathology of dental follicle of impacted teeth using modified gallego's and H and E stain

open access: yesJournal of the Scientific Society, 2022
Background: Dental follicles are involved the development of tooth and periodontal structures. Dental follicles are known for pleuripotency and inductive changes but are also known for origin for various pathologies.

Aberrant Epithelial Cell Proliferation in Peripheral Airways in Bronchiectasis

open access: yesFrontiers in Cell and Developmental Biology, 2020
Dilation of bronchi and bronchioles caused by destruction and excessive epithelial remodeling is a characteristic feature of bronchiectasis. It is not known how epithelial progenitor cells contribute to these pathologic conditions in peripheral airways ...

Kinetics of 5-aminolevulinic acid-induced fluorescence in organ cultures of bronchial epithelium and tumor [PDF]

open access: yes, 2002
Background: 5-Aminolevulinic acid (5-ALA)-induced protoporphyrin IX (PPIX) fluorescence improves the differentiation of tumor and normal tissue in the bladder, skin and brain. Objective: The kinetics of 5-ALA-induced protoporphyrin IX (PPIX) fluorescence

Immunomodulation of Epithelium [PDF]

open access: yesCanadian Journal of Gastroenterology, 1994
Many studies have provided evidence that the immune system is a key regulatory system of intestinal function. The interaction of immune cells with the gut epithelium plays an important role in host defence, acting to eliminate pathogens, antigens and other noxious material from the lumen of the gastrointestinal tract.

Biofilm-stimulated epithelium modulates the inflammatory responses in co-cultured immune cells [PDF]

open access: yes, 2019
The gingival epithelium is a physical and immunological barrier to the microbiota of the oral cavity, which interact through soluble mediators with the immune cells that patrol the tissue at the gingival epithelium.

Effect of aging on endogenous level of 5 alpha-dihydrotestosterone, testosterone, estradiol, and estrone in epithelium and stroma of normal and hyperplastic human prostate. [PDF]

open access: yes, 1993
associated with aging. Thus, the question arises whether or not a correlation exists between the well known prostatic androgen and estrogen accumulation and aging.

Spread of premalignant mutant clones and cancer initiation in multilayered tissue [PDF]

open access: yesAnnals of Applied Probability 33(1) (2023) 299-343, 2020
Over 80% of human cancers originate from the epithelium, which covers the outer and inner surfaces of organs and blood vessels. In stratified epithelium, the bottom layers are occupied by stem and stem-like cells that continually divide and replenish the upper layers. In this work, we study the spread of premalignant mutant clones and cancer initiation
