December 2012 in “EMBO Reports” This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.
115 citations
,
September 2012 in “Experimental Dermatology” This article reviews the molecular mechanisms involved in androgenetic alopecia and the androgen's paradoxical role in hair growth, but reports no new experimental findings.
29 citations
,
September 2012 in “Birth Defects Research” This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.
207 citations
,
March 2012 in “Development” In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.
95 citations
,
January 2012 in “British Journal of Dermatology” This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.
19 citations
,
September 2011 in “Journal of Dermatological Science” TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.
333 citations
,
February 2010 in “Cell Stem Cell” This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.
70 citations
,
January 2009 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.
44 citations
,
January 2006 in “Biological & Pharmaceutical Bulletin” This research suggests that testosterone-induced expression of TGF-beta1 and type I procollagen may lead to perifollicular fibrosis in androgenetic alopecia, with finasteride inhibiting this process as a possible mechanism for its effects.
190 citations
,
October 2002 in “The FASEB journal” In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.
140 citations
,
December 1998 in “Journal of Investigative Dermatology” Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.
385 citations
,
November 1990 in “Journal of Cell Science” This study successfully grew and maintained human hair follicles in vitro, noting that TGF-β1 negatively affects growth, while EGF replicates hair-removal effects seen in animals.
