Patterns of Expression of Trichocytic and Epithelial Cytokeratins in Mammalian Tissues

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study found that monoclonal antibodies can identify specific immunological characteristics of hair fibrous proteins, with some antibodies reacting only with hair proteins and others showing broader activity with skin and epithelial cells.

This study observed that the expression of certain keratins during human epidermal development marks the tissue's commitment to stratification and keratinization processes.

This study found that the cytokeratin patterns in skin epithelia can distinguish between different types, with basal-cell epitheliomas showing a striking similarity to the pilosebaceous tract.

This study demonstrated that keratin is widely present in various epithelial cells, providing structural strength and potential insights into the origin of cell lines.
