May 2008 in “Development” This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.
253 citations
,
April 2008 in “Current opinion in cell biology” This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.
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.
153 citations
,
October 2007 in “Cell Stem Cell” New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.
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.
829 citations
,
May 2007 in “Nature” Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.
291 citations
,
October 2005 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that rat whisker follicle stem cells can be expanded in culture and transplanted to form functional hair follicles, demonstrating their multipotency and potential for regenerative medicine.
335 citations
,
March 2004 in “Development” This study found that continuous β-catenin signaling in adult mouse epidermis can reprogram hair follicles to form benign tumors, which regress after the signaling is discontinued.
387 citations
,
November 2003 in “Journal of Investigative Dermatology” The K15 promoter effectively targets stem cells in the hair follicle bulge.
421 citations
,
September 2003 in “Development” This study concluded that label-retaining cells in mouse epidermis differ in their sensitivity to proliferative stimuli, influencing their division and potential transdifferentiation without consistently depleting their population.
555 citations
,
July 2001 in “Genes & Development” This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.
137 citations
,
April 2001 in “Journal of Clinical Investigation” This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.
338 citations
,
April 2001 in “Current Biology” This study found that transient activation of c-Myc in transgenic mice stimulates keratinocyte proliferation and sebocyte differentiation, affecting normal epidermal and hair follicle development.
990 citations
,
October 1999 in “Development” This study found that LEF1/TCF3 is necessary but not sufficient for TOPGAL activation in hair follicle development, indicating complex regulation in the skin.
467 citations
,
May 1999 in “Molecular Cell” In this study, activation of c-MycER in adult mouse epidermis rapidly induced proliferation and disrupted keratinocyte differentiation, causing changes similar to precancerous lesions, which regressed once c-MycER was deactivated.
