July 1999 in “The EMBO Journal” Overexpression of certain genes can shorten hair by disrupting the hair-growth cycle.
148 citations
,
October 1997 in “Journal of Investigative Dermatology” TGF-β receptors are crucial for hair follicle development.
33 citations
,
January 1997 in “Endocrinology” Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.
154 citations
,
October 1996 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.
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.
71 citations
,
May 1996 in “Journal of Investigative Dermatology” This study found that overexpression of a mutated ornithine decarboxylase transgene in mice led to complete hair loss, which could be prevented or reversed with an ODC inhibitor.
46 citations
,
May 1995 in “Proceedings of the National Academy of Sciences” This study demonstrated that a specific 9-kbp fragment of the bovine keratin 6 gene effectively directs tissue-specific and inducible expression in transgenic mice, suggesting potential applications for targeted gene therapy in hyperproliferative skin conditions.
14 citations
,
March 1995 in “Journal of cell science” This study found that targeting SV40 T antigen expression to hair follicles in transgenic mice caused abnormal hair structure and hair loss, but did not lead to cell immortalization or tumor formation in follicles.
13 citations
,
July 1994 in “PubMed” This study found that TPA treatment induced expression of keratins K6 and K16 in mouse epidermis, with K6 expressed across all cell layers and K16 only in post-mitotic cells.
130 citations
,
January 1994 in “Differentiation” In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.
39 citations
,
July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that daily injections of basic and acidic fibroblast growth factor in newborn mice significantly delayed hair follicle development within the treatment area, while epidermal growth factor affected the entire body coat and caused skin hyperkeratinization.
265 citations
,
March 1993 in “The EMBO Journal” Keratinocyte growth factor significantly alters skin and tissue development.
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.
198 citations
,
November 1989 in “The Journal of Cell Biology” This study reported that K14 expression patterns and keratin filament organization in human skin's hair follicles differ from those in the epidermis, indicating distinct differentiation programs.
135 citations
,
November 1987 in “Differentiation” This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.
