June 2019 in “Nature Communications” This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.
163 citations
,
April 2019 in “Nature Communications” This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.
101 citations
,
March 2019 in “Cell Stem Cell” This study found that Oncostatin M, via JAK-STAT5 signaling, keeps hair follicle stem cells inactive, and its removal leads to hair growth initiation in mice.
145 citations
,
November 2018 in “Nature Communications” This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.
209 citations
,
October 2018 in “Cell Reports” This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.
27 citations
,
May 2018 in “Journal of Dermatological Science” This study suggests that M2 macrophages play a key role in promoting wound-induced hair neogenesis in mice by producing growth factors like Igf1 and Fgf2.
84 citations
,
January 2018 in “Biomaterials Science” Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.
20 citations
,
July 2017 in “Journal of Investigative Dermatology” IL-1 receptor absence in mice leads to skin cysts and changes in immune response after UVB exposure.
117 citations
,
March 2017 in “Nature Communications” This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.
192 citations
,
March 2017 in “Cell host & microbe” The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.
408 citations
,
January 2017 in “Science” This study found that hair follicles in mice and humans can convert wound-related myofibroblasts into adipocytes, suggesting a potential pathway to reduce scar formation by activating BMP signaling.
128 citations
,
August 2015 in “Cell Stem Cell” The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.
237 citations
,
June 2013 in “Nature Medicine” This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.
68 citations
,
November 2012 in “Journal of Investigative Dermatology” This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.
829 citations
,
May 2007 in “Nature” Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.
