This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

In this study, the novel ASAXA-μCT imaging method identified that the shrinkage of sweat glands with aging causes dermal defects, reducing skin elasticity and contributing to wrinkling and sagging.

This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This study highlights a paradox where valproic acid, known for causing hair loss, may also promote hair growth when applied topically.

This article discusses the paradoxical effects of valproic acid on hair, reporting both drug-induced hair loss and the potential for hair growth when used topically, but presents no original research findings.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This study found that WNT10A is significantly upregulated in human esophageal squamous cell carcinoma and is associated with enhanced tumor cell migration, invasion, and poor survival.

This review discusses recent advancements in the management and diagnosis of primary cicatricial alopecias but reports no new clinical results; emerging insights suggest sebaceous gland dysfunction may play a role in their etiopathogenesis.

This study identified three genes with significantly higher expression in androgen-sensitive beard dermal papilla cells compared to androgen-insensitive scalp cells, suggesting potential novel signaling pathways in hair follicles.

This study found that white hair exhibits increased expression of genes and proteins linked to active hair growth compared to black hair, suggesting that hair greying is associated with enhanced hair growth activity.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.

This study developed a new protocol to efficiently produce skin dermal stem cells from human induced pluripotent stem cells, which may aid in treating various skin disorders.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

In this study, overexpression of Wnt5a in mice was associated with the elongation of the telogen stage and inhibition of hair growth initiation, suggesting Wnt5a's role in maintaining hair follicle quiescence.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

This study identified a specific subpopulation of hair follicle stem cells in mice and humans that are essential for long-term hair regeneration, highlighting the potential for regenerative therapy.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

This study found that mutations in the hairless gene disrupt normal hair follicle development by impairing Wnt/β-catenin signaling, affecting hair keratinocyte differentiation in both mice and humans.

This article reviews the role of KLF4, a transcription factor, in various cellular processes and its dual function as a tumor suppressor or oncogene depending on the context, but presents no new experimental results.
