Research cited in this study

20 / 20 results

research Susceptibility Variants for Male-Pattern Baldness on Chromosome 20p11

140 citations , October 2008 in “Nature Genetics”

research Human Hair Follicles Contain Two Forms of ATP-Sensitive Potassium Channels, Only One Sensitive to Minoxidil

102 citations , February 2008 in “The FASEB Journal”

This study found that human hair follicles express ATP-sensitive potassium channels, suggesting that minoxidil acts on these channels and that drugs targeting them may treat hair disorders.

research Dihydrotestosterone-Inducible Dickkopf 1 from Balding Dermal Papilla Cells Causes Apoptosis in Follicular Keratinocytes

171 citations , July 2007 in “Journal of Investigative Dermatology”

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

research Adenosine Stimulates Fibroblast Growth Factor-7 Gene Expression Via Adenosine A2b Receptor Signaling in Dermal Papilla Cells

66 citations , February 2007 in “The journal of investigative dermatology/Journal of investigative dermatology”

The researchers reported that adenosine increases FGF-7 expression in dermal papilla cells, which may stimulate hair growth via the A2b adenosine receptor and cAMP pathway.

research Different Gene Expression Profile Observed in Dermal Papilla Cells Related to Androgenic Alopecia by DNA Macroarray Analysis

47 citations , July 2004 in “Journal of Dermatological Science”

In this study, decreased expression of BMP2 and ephrin A3 and increased NT-4 gene expression were observed in dermal papilla cells from androgenic alopecia-affected skin, suggesting potential roles in hair growth regulation.

research Minoxidil Opens Mitochondrial KATP Channels and Confers Cardioprotection

28 citations , January 2004 in “British Journal of Pharmacology”

This study found that minoxidil provides cardioprotective effects in guinea-pig heart cells through selective activation of mitochondrial ATP-sensitive potassium channels.

Androgen-Inducible TGF-β1 from Balding Dermal Papilla Cells Inhibits Epithelial Cell Growth: A Clue to Understanding Paradoxical Effects of Androgen on Human Hair Growth

research Androgen-Inducible TGF-β1 from Balding Dermal Papilla Cells Inhibits Epithelial Cell Growth: A Clue to Understanding Paradoxical Effects of Androgen on Human Hair Growth

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.

Minoxidil-Induced Hair Growth Is Mediated by Adenosine in Cultured Dermal Papilla Cells: Possible Involvement of Sulfonylurea Receptor 2B as a Target of Minoxidil

research Minoxidil-Induced Hair Growth Is Mediated by Adenosine in Cultured Dermal Papilla Cells: Possible Involvement of Sulfonylurea Receptor 2B as a Target of Minoxidil

83 citations , December 2001 in “Journal of Investigative Dermatology”

Minoxidil boosts hair growth by targeting adenosine and possibly sulfonylurea receptor 2B.

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 Hair Cycle-Dependent Expression of Hepatocyte Growth Factor Activator, Other Proteinases, and Proteinase Inhibitors Correlates with the Expression of Hepatocyte Growth Factor in Rat Hair Follicles

33 citations , December 1999 in “Journal of Investigative Dermatology Symposium Proceedings”

research Minoxidil Upregulates the Expression of Vascular Endothelial Growth Factor in Human Hair Dermal Papilla Cells

192 citations , March 1998 in “British Journal of Dermatology”

This study found that minoxidil significantly increases VEGF mRNA and protein expression in dermal papilla cells, suggesting a role in enhancing hair follicle vascularization in androgenetic alopecia.

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 In the Absence of Streptomycin, Minoxidil Potentiates the Mitogenic Effects of Fetal Calf Serum, Insulin-Like Growth Factor 1, and Platelet-Derived Growth Factor on NIH 3T3 Fibroblasts in a K+ Channel-Dependent Fashion

32 citations , August 1996 in “Journal of Investigative Dermatology”

research Effects of Hypertrichotic Agents on Follicular and Nonfollicular Cells In Vitro

28 citations , January 1996 in “Skin Pharmacology and Physiology”

This study observed that minoxidil specifically increased DNA synthesis in hair follicle cells, suggesting its distinct mechanism of action in promoting hair growth compared to cyclosporin, which showed no direct proliferative effect on these cells.

research Vascular Endothelial Growth Factor Is an Autocrine Growth Factor for Hair Dermal Papilla Cells

135 citations , January 1996 in “Journal of Investigative Dermatology”

research Loss of Vascular Endothelial Growth Factor in Human Alopecia Hair Follicles

47 citations , May 1995 in “Journal of Investigative Dermatology”

Hair follicles in people with alopecia have lower levels of a key blood vessel growth protein.

research Quantitative Models for the Study of Hair Growth In Vivo

34 citations , December 1991 in “Annals of the New York Academy of Sciences”

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.

research The Hair Growing Effect of Minoxidil

9 citations , December 1991 in “Annals of the New York Academy of Sciences”

Minoxidil helps hair growth by increasing blood flow and stimulating hair follicles.

research The Stumptailed Macaque as a Model for Baldness: Effects of Minoxidil

18 citations , April 1986 in “International Journal of Cosmetic Science”

In this study with stumptailed macaques, topical minoxidil successfully induced hair regrowth on bald scalps and prevented baldness on non-bald scalps, with no observed side effects over nearly three years.
