Abstract
BACKGROUND Recent research reports that VEGFR-2 is expressed in the whole hair follicle, sebaceous glands, eccrine sweat glands, and epidermis. However, phosphorylated VEGFR-2 was not found, and it could not be ascertained whether the activated form of VEGFR-2 actually participates in the biological control of epidermal appendages. In this study we aimed to determine whether the VEGFR-2 pathway is directly involved in the daily regulation of epidermal appendages biology. MATERIAL AND METHODS In this study, we investigated the expression of phosphorylation of VEGFR-2 by immunohistochemical analysis in the epidermis and epidermal appendages in normal human scalp skin. RESULTS Immunohistochemical analysis revealed phosphorylation of VEGFR-2 in a whole hair follicle, mainly in the infundibulum basal layer, hair cortex, and medulla in the isthmus, and matrix in the hair bulb. Phosphorylated VEGFR-2 also was found in the sebaceous glands, eccrine sweat glands, and epidermis. CONCLUSIONS Therefore, we suggest that VEGFR-2 activation is involved in routine regulation of human epidermal appendages.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
