April 2012 in “Physiology” This article explores how extrafollicular environments and stem cell configurations influence hair and feather regeneration but provides no new experimental results.
176 citations
,
April 2011 in “Science” This study found that in a population of hair follicles, regenerative cycling stages are regulated by both intrinsic and extrinsic signals, with WNT/BMP signaling mediating interactions among follicles for adaptability.
103 citations
,
March 2011 in “PLoS Biology” This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.
55 citations
,
November 2010 in “Development” This study observed that in frizzled 6 null mice, initially uncorrelated hair follicle orientations develop into highly ordered patterns over time, suggesting possible mechanisms for biological structure patterning.
1039 citations
,
February 2009 in “Nature Reviews Molecular Cell Biology” This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.
88 citations
,
July 2008 in “Development” This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.
193 citations
,
May 2008 in “Development” This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.
427 citations
,
April 2008 in “Nature Protocols” 
127 citations
,
December 2007 in “Journal of Investigative Dermatology” This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.
57 citations
,
May 2007 in “Nature” This study suggests that wounding skin in adult mice can trigger new hair follicle formation, indicating mammalian skin may have greater regenerative capacity than previously thought.
829 citations
,
May 2007 in “Nature” Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.
85 citations
,
October 2006 in “Current opinion in cell biology” This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.
38 citations
,
November 2005 in “Journal of Investigative Dermatology Symposium Proceedings” 
122 citations
,
July 2005 in “The FASEB journal” This study found that hair follicles in both mice and humans may serve as an important site for melatonin synthesis and signaling, potentially influencing hair cycle regulation by modulating keratinocyte apoptosis.
205 citations
,
April 2005 in “Journal of Investigative Dermatology” This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.
23 citations
,
December 2004 in “Differentiation” This article reviews the interaction between sex hormone pathways and morphogenesis-related signaling in epithelial organ development, using a chicken model to propose testable hypotheses, but reports no new clinical results.
112 citations
,
January 2004 in “The International journal of developmental biology” This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.
176 citations
,
January 2003 in “Journal of Investigative Dermatology” This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.
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.
249 citations
,
April 2002 in “The FASEB journal” This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.
