This study shows that alpha 6 + /MHCI - cells have gene expression profiles similar to hair follicle stem cells, suggesting they may be enriched for stem cells.

This study discovered a novel mechanism by which germ stem cells exit their niche in C. elegans, involving thin membranous protrusions from adjacent somatic gonad cells.

This study found that the RNA helicase DDX6 is essential for maintaining self-renewal in epidermal progenitor cells by promoting the translation of proliferation regulators and degrading differentiation-inducing mRNAs.

This study concluded that the increase in NGF mRNA levels during mouse whisker pad development is influenced by soluble factors produced within the tissue, rather than linked to epidermal differentiation.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study revealed that BMP5 in onychofibroblasts may play a key role in the differentiation of nail matrix keratinocytes, highlighting transcriptional similarities between nail and hair structures.

This study found that fibronectin supports hair follicle regeneration by influencing stem cell behavior through integrin-dependent mechanotransduction, highlighting its potential role in epidermal renewal.

Protease Nexin-1 is found in human hair growth cells and is affected by male hormones.

This study found that the Wnt pathway activator lithium chloride promotes proliferation and odontoblast differentiation of hair follicle neural crest cells.

This research suggests that hair keratins evolved from claw keratins in a hairless ancestor, with Hoxc13 controlling their expression in tetrapods, evidenced by the knockout of Hoxc13 hindering claw formation in Xenopus tropicalis frogs.

This article reviews how aging affects skin and stem cells, but it contains no new research findings.

This study found that distinct low-threshold mechanoreceptors innervate different hair follicle types in mice, suggesting that these follicles serve as unique mechanosensory structures in touch perception.

This study showed that a 2-kilobase upstream region of the mouse keratin 17 gene enables targeted GFP expression in major epithelial appendages of transgenic mice, indicating sonic hedgehog's involvement in its regulation.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This study established a Krt24-CreERT2 mouse line targeting outer bulge hair follicle stem cells, finding these cells crucial for hair follicle development and repair, particularly following ionizing radiation exposure.

This study found that increased intracellular expression of thymosin β4 is necessary and sufficient to induce PAI-1 gene expression in endothelial cells, potentially mediated through Ku80 as a novel receptor.

This review examines the roles of Smad-4 and Smad-7 in hair follicle differentiation and development through BMP signaling and TGFβ/Activin/BMP pathway inhibition but reports no new experimental results.

In this study, researchers found that the FoxN1, FoxE1, and FoxI3 genes are likely involved in hair follicle growth and development in cashmere goat fetuses.

This study suggests that over-expression of Sp2 may limit stem cell differentiation and contribute to tumorigenic cell growth in mice.

This study observed that GREM2 was specifically and robustly expressed in the dermal sheath cup of hair follicles during various hair cycle phases, suggesting its significant role in regulating hair cycling processes through BMP signaling.

This study describes a genetic mutation in the desmoglein 4 gene linked to localized autosomal recessive hypotrichosis in Pakistani families, showing similarities to animal models with similar hair loss conditions.

This study indicates that transient Msx2 expression is critical for wound-induced hair follicle neogenesis, with distinct phases in the healing process essential for epidermal competence and hair regeneration.

This study observed that overexpression of Bcl-2 in certain transgenic mice accelerates catagen progression and increases hair follicle apoptosis and alopecia, while Bcl-2 deficient mice show delayed hair growth and pigmentation changes.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

This study reports that the mouse Scube3 gene is expressed in various tissues during embryonic development, including the neural tube, limb buds, developing tooth, hair follicle, and skeletal regions.

In this study, naked mole-rats demonstrated unique skin and hair follicle innervation features compared to other species, suggesting adaptations to their subterranean environment and poikilothermy.
