August 2008 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.
34 citations
,
June 2008 in “In vitro cellular & developmental biology. Animal” This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.
1398 citations
,
May 2008 in “Histochemistry and Cell Biology” This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.
45 citations
,
December 2007 in “The FASEB journal” This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.
9 citations
,
July 2007 in “Journal of Investigative Dermatology” This study found that exposure to 12-O-tetradecanoyl-phorbol-13-acetate in mouse skin caused changes in claudin expression and localization, indicating disruption and eventual recovery of the epidermal barrier.
788 citations
,
February 2007 in “Nature” This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.
63 citations
,
April 2005 in “Mechanisms of development” This study found that heterozygous mice overexpressing Claudin-6 experienced alterations in epidermal and hair follicle differentiation, leading to distinctive coat characteristics and a disrupted epidermal permeability barrier.
233 citations
,
October 2004 in “Differentiation” Stem cells are in deep skin layers, while differentiating cells are in shallow layers.
387 citations
,
November 2003 in “Journal of Investigative Dermatology” The K15 promoter effectively targets stem cells in the hair follicle bulge.
198 citations
,
March 1999 in “Journal of Investigative Dermatology” This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.
46 citations
,
November 1998 in “Experimental Cell Research” This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.
318 citations
,
October 1998 in “The Journal of Cell Biology” This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.
238 citations
,
October 1994 in “Current opinion in genetics & development” This article reviews the role of epidermal proteins and regulatory mechanisms in skin diseases, emphasizing recent insights but reports no new experimental results.
198 citations
,
November 1989 in “The Journal of Cell Biology” This study reported that K14 expression patterns and keratin filament organization in human skin's hair follicles differ from those in the epidermis, indicating distinct differentiation programs.
