March 2017 in “Endocrinology” In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.
86 citations
,
August 2015 in “The Journal of Steroid Biochemistry and Molecular Biology” This study suggests that vitamin D and calcium signaling play a crucial role in wound healing by regulating stem cell activation through enhanced β-catenin transcriptional activity in mice.
56 citations
,
September 2014 in “Molecular Endocrinology” This study found that the absence of unliganded vitamin D receptor significantly impairs cWnt and hedgehog signaling pathways necessary for hair cycle initiation in VDR-null mice.
20 citations
,
August 2014 in “PloS one” This study found that MED1 deficiency in keratinocytes accelerates skin wound healing in young mice but delays healing in older mice, suggesting differential roles in epidermal regeneration with age.
173 citations
,
January 2014 in “Nature Cell Biology” This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.
57 citations
,
January 2014 in “Cold Spring Harbor Perspectives in Medicine” Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.
133 citations
,
September 2013 in “Nature Reviews Molecular Cell Biology” Different types of stem cells and their environments are key to skin repair and maintenance.
56 citations
,
November 2012 in “Endocrinology” This study found that the absence of vitamin D receptor signaling in mice impairs the inflammatory response to skin injury, particularly affecting macrophage recruitment and granulation tissue formation.
156 citations
,
October 2012 in “Seminars in Cell & Developmental Biology” This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.
503 citations
,
May 2009 in “Cell stem cell” This study suggests that Lrig1-positive cells form a previously unknown reservoir of interfollicular epidermal stem cells in adult mouse skin, influencing epidermal proliferation and hair follicle development.
25 citations
,
March 2008 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that while VDR is crucial for maintaining hair follicles in mice, their degeneration may be linked to impaired cell migration during hair growth phases rather than stem cell loss.
127 citations
,
January 2008 in “PloS one” This study observed that the vitamin D receptor is crucial for hair follicle formation and altering tumor development in the Wnt signaling pathway, suggesting therapeutic potential for vitamin D analogues in related tumors.
170 citations
,
November 2007 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that in the absence of hair follicles, cutaneous wounds in mice showed delayed reepithelialization but eventually achieved normal wound closure after expanding the activated epidermis region.
143 citations
,
May 2007 in “Proceedings of the National Academy of Sciences” This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.
81 citations
,
January 2006 in “Journal of cellular physiology” This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.
1279 citations
,
November 2005 in “Nature Medicine” 180 citations
,
January 2002 in “The journal of investigative dermatology/Journal of investigative dermatology” This study observed that vitamin D receptor knockout mice exhibit impaired epidermal differentiation and progressive hair loss, suggesting the importance of the vitamin D receptor in normal skin and hair follicle development.
