In this study using a mouse model, Prom1+ dermal papilla cells were found to regulate the size of the papilla via β-catenin communication but did not aid in dermal repair.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

This study found that combining LED yellow light with an engineered strain expressing CXCL12 improved wound healing and reduced inflammation in a mouse model of scald wounds.

This study found that activating TRPV4 in the skin of mice induced hair follicle regeneration by promoting anagen transition, suggesting potential treatment strategies for hair loss.

This narrative review discusses the discovery of plasticity in epidermal stem cells using single-cell transcriptomics, but reports no new results; it highlights the potential implications for regenerative medicine.

This study found that certain circulating miRNAs in skin and plasma may serve as potential biomarkers for distinguishing frontal fibrosing alopecia from control cases, highlighting the need for further validation in larger cohorts.

This study re-analyzed single cell RNAseq data and confirmed longstanding views on keratin gene regulation in keratinocytes, while challenging assumptions about their role in cellular differentiation states.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

This study found that nobiletin-loaded vesicles effectively restored skin condition in a mouse model of skin cancer, suggesting they are a promising treatment delivery system.

This study observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.

This study found that epidermal-specific deletion of integrin α3β1 significantly reduces papilloma formation in a skin carcinogenesis model by modulating HB stem cell behavior and CCN2 expression.

This study examined variations in epidermal thickness and protein expression across different dog breeds, finding significant differences by anatomical site and breed, with associated mRNA and protein expression changes observed.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

The researchers reported that Lrig1 overexpression was observed in 100% of sebaceous carcinoma cases, suggesting it may serve as a potential marker for poorly differentiated sebaceous carcinoma.

This study suggests that human placenta treatment may promote hair regrowth in chemotherapy-induced alopecia by inhibiting apoptosis and encouraging hair follicle proliferation in a mouse model.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This study found that adiponectin promotes hair growth in cultured human hair follicles, suggesting its receptors could be a target for clinical hair growth strategies.

This study found that overexpression of Gsdma3 in mice led to epidermal hyperplasia, skin inflammation, and hair growth defects, suggesting gain-of-function mutations in Gsdma3 cause these conditions.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

This study identified the dermal sheath as a key component of the hair follicle niche, essential for outer root sheath regression during the hair cycle, highlighting its importance in hair follicle support and regulation.

This study found that inhibiting JAK signaling can unexpectedly trigger hair growth in resting-phase mouse skin, implicating JAK-STAT pathways and oncostatin M in maintaining hair follicle stem cell quiescence.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.

The new treatment was safe and may effectively treat male pattern hair loss.

The new baby shampoo and wash with stearic acid is safe and potentially effective for nourishing babies' skin.

This study explores the complex mechanisms of skin aging, including cellular senescence and disrupted communication, and highlights rejuvenation strategies like gene expression rewiring and microbiome modulation, offering potential frameworks for regenerative therapies and precise interventions in skin and systemic aging.

This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

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.
