June 2017 in “International Journal of Radiation Biology” This review of murine studies reports that γ-rays affect hair follicle pigmentation in mice throughout the hair cycle, while effects on hair structure may be obscured by aging.
242 citations
,
February 2016 in “Science” This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.
5 citations
,
November 2015 in “International Journal of Radiation Biology” This study suggests that gamma-ray irradiation affects hair follicle density, structure, and pigmentation in mice, with some changes observed in later hair cycles.
20 citations
,
January 2015 in “Current problems in dermatology” This paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.
6 citations
,
November 2013 in “International Journal of Radiation Biology” In this study, γ-ray irradiation of mice reduced hair follicle density and pigmentation, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.
30 citations
,
April 2013 in “Journal of Investigative Dermatology” This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.
170 citations
,
July 2012 in “Journal of Investigative Dermatology” In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.
283 citations
,
February 2011 in “Cell stem cell” COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem cells.
717 citations
,
June 2010 in “Nature” This study identified key genetic regions associated with alopecia areata, highlighting both acquired and innate immune involvement, with a novel link to the upregulation of ULBP ligands in autoimmune disease.
253 citations
,
December 2007 in “Journal of Investigative Dermatology” This study suggests that human hair follicles may actively suppress natural killer cells, which contrasts with the observed defects in NK cell regulation in alopecia areata.
387 citations
,
November 2003 in “Journal of Investigative Dermatology” The K15 promoter effectively targets stem cells in the hair follicle bulge.
90 citations
,
October 1996 in “Dermatologic Clinics” This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.
578 citations
,
April 1993 in “Cell” This study found that mice with a disrupted TGFα gene display a curly whisker-coat phenotype, similar to waved-1 mice, suggesting TGFα's crucial role in skin architecture and hair development.
521 citations
,
January 1954 in “Physiological Reviews” Hair growth is cyclic and influenced mainly by local factors.
