research A Family Business: Stem Cell Progeny Join the Niche to Regulate Homeostasis

254 citations , January 2012 in “Nature Reviews Molecular Cell Biology”

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

research Paracrine TGF-β Signaling Counterbalances BMP-Mediated Repression in Hair Follicle Stem Cell Activation

321 citations , January 2012 in “Cell stem cell”

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

research Genome-Wide Maps of Histone Modifications Unwind In Vivo Chromatin States of the Hair Follicle Lineage

191 citations , September 2011 in “Cell stem cell”

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

research Adipocyte Lineage Cells Contribute to the Skin Stem Cell Niche to Drive Hair Cycling

499 citations , September 2011 in “Cell”

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

research Coordinated Activation of Wnt in Epithelial and Melanocyte Stem Cells Initiates Pigmented Hair Regeneration

260 citations , June 2011 in “Cell”

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

research Nerve-Derived Sonic Hedgehog Defines a Niche for Hair Follicle Stem Cells Capable of Becoming Epidermal Stem Cells

396 citations , May 2011 in “Cell stem cell”

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

research The Basement Membrane Of Hair Follicle Stem Cells Is A Muscle Cell Niche

294 citations , February 2011 in “Cell”

Nephronectin helps attach muscle cells to hair follicles.

research Beta-Catenin Activity in the Dermal Papilla Regulates Morphogenesis and Regeneration of Hair

314 citations , April 2010 in “Developmental Cell”

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

research Epidermal Homeostasis: A Balancing Act of Stem Cells in the Skin

1039 citations , February 2009 in “Nature Reviews Molecular Cell Biology”

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

research Scratching the Surface of Skin Development

788 citations , February 2007 in “Nature”
