May 2014 in “Naunyn-Schmiedeberg's Archives of Pharmacology” In this study, 7-phloroeckol, derived from marine brown algae, was found to promote hair growth by increasing cell proliferation and hair shaft elongation in cultured human hair follicles.
24 citations
,
April 2012 in “Developmental Biology” This animal study found that dermal papilla cells in hair follicles of chimeric mice can originate from various fibroblasts in the skin, challenging assumptions about their specific lineage.
January 2006 in “Chinese Journal of Dermatology” This study found that cultured dermal papilla cells can induce hair follicle regeneration and sustain hair growth both in vivo and in vitro, with their effectiveness linked to specific protein expression levels.
90 citations
,
August 2004 in “Physiological Genomics” This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.
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.
5 citations
,
May 2004 in “International Journal of Cosmetic Science” This study demonstrated that the large molecule versican plays a critical role in hair induction in dermal papilla cells, with potential implications for developing new hair growth treatments.
1 citations
,
January 2004 in “Linchuang pifuke zazhi” This study found that while SP did not enhance linear hair growth in cultured hair follicles, it prolonged the anagen phase and altered the expression of growth factors and apoptosis-related molecules, suggesting a stimulatory effect on hair growth.
1 citations
,
January 2004 in “Linchuang pifuke zazhi” This study found that dermal hair papilla and sheath cells have lower collagen secretion than fibroblasts, suggesting different functions, and that routine culture medium supports their optimal growth and proliferation.
February 2001 in “Chinese Journal of Dermatology” This study observed that epidermal growth factor significantly stimulated the growth of dermal papilla cells, dermal sheath cells, and fibroblasts in vitro, which supports its use in organotypic culture.
January 2000 in “Acta Academiae Medicine Militaris Tertiae” This study observed that epidermal growth factor significantly enhanced the growth of dermal papilla, dermal sheath cells, and fibroblasts in vitro, particularly benefiting dermal sheath cells.
