Research cited in this study

15 / 15 results

research Destruction of the Arrector Pili Muscle and Fat Infiltration in Androgenic Alopecia

35 citations , March 2014 in “British Journal of Dermatology”

This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.

research The Basement Membrane Of Hair Follicle Stem Cells Is A Muscle Cell Niche

294 citations , February 2011 in “Cell”

Nephronectin helps attach muscle cells to hair follicles.

research Review of Hair Follicle Dermal Cells

321 citations , December 2009 in “Journal of Dermatological Science”

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

research The Mesenchymal Component of Hair Follicle Neogenesis: Background, Methods, and Molecular Characterization

131 citations , July 2009 in “Experimental Dermatology”

This review discusses the development and advances in studying trichogenic dermal cells for hair follicle morphogenesis, summarizing methods, bioassays, and molecular markers, but reports no new research findings.

The Ludwig Pattern of Androgenetic Alopecia Is Due to a Hierarchy of Androgen Sensitivity Within Follicular Units That Leads to Selective Miniaturization and a Reduction in the Number of Terminal Hairs Per Follicular Unit

research The Ludwig Pattern of Androgenetic Alopecia Is Due to a Hierarchy of Androgen Sensitivity Within Follicular Units That Leads to Selective Miniaturization and a Reduction in the Number of Terminal Hairs Per Follicular Unit

47 citations , September 2008 in “British Journal of Dermatology”

This study found that women with androgenetic alopecia experience diffuse hair loss due to a decrease in terminal hairs and an increase in vellus hairs per follicular unit.

research Sexual Hormones in Human Skin

305 citations , February 2007 in “Hormone and metabolic research”

This review discusses the roles of androgens and estrogens in skin functions and disorders, and highlights the use of estrogen-progestin treatments and anti-androgens in managing hirsutism and acne, without reporting new results.

research Biology of the Wool Follicle: An Excursion into a Unique Tissue Interaction System Waiting to Be Rediscovered

117 citations , November 2006 in “Experimental Dermatology”

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

research Characterization and Isolation of Stem Cell-Enriched Human Hair Follicle Bulge Cells

550 citations , December 2005 in “The Journal of clinical investigation/The journal of clinical investigation”

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.

research Control of Hair Growth and Follicle Size by VEGF-Mediated Angiogenesis

520 citations , February 2001 in “Journal of Clinical Investigation”

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

research Morphogenesis and Renewal of Hair Follicles from Adult Multipotent Stem Cells

949 citations , January 2001 in “Cell”

This study demonstrated that multipotent stem cells in adult mice whisker follicles migrate to produce whisker growth, and that this process requires precise control of stem cell trafficking.

research Balding Hair Follicle Dermal Papilla Cells Contain Higher Levels of Androgen Receptors Than Those From Non-Balding Scalp

227 citations , January 1998 in “Journal of Endocrinology”

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

research Characterization of Hair Follicle Bulge in Human Fetal Skin: The Human Fetal Bulge Is a Pool of Undifferentiated Keratinocytes

96 citations , December 1995 in “Journal of Investigative Dermatology”

research The Secret Life of the Hair Follicle

745 citations , February 1992 in “Trends in genetics”

This article describes the potential role of various growth factors and molecules in regulating mammalian hair follicle development but does not present new experimental results.

research Dynamic Ultrastructural Changes of the Connective Tissue Sheath of Human Hair Follicles During the Hair Cycle

44 citations , October 1990 in “Archives of Dermatological Research”

The connective tissue around hair follicles changes structure throughout the hair cycle.

research The Cytology and Cytochemistry of the Wool Follicle

90 citations , January 1979 in “International review of cytology”

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.
