This study found that 64.8% of patients with different types of alopecia had vitamin D deficiency, and those with lichen planopilaris and telogen effluvium had higher odds of severe deficiency compared to patients with alopecia areata.

This review discusses the roles of αβ and γδ T cells in skin health and disease and reports no new clinical results; the authors highlight potential therapeutic developments.

This study discusses two cases of acneiform skin eruptions associated with the use of the EGFR inhibitor ZD1839 in prostate cancer treatment, emphasizing the need for dermatologists to be aware of potential skin reactions.

In this review, retinoids are highlighted as promising agents for promoting scarless skin regeneration by coordinating cellular and molecular processes that suppress fibrosis, enhance re-epithelialization, promote angiogenesis, and enable hair follicle formation, potentially advancing functional skin repair.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This review discusses the role of umbilical cord-derived mesenchymal stromal cells in skin rejuvenation and reports no new clinical results; it emphasizes their potential in delaying skin aging.

This study found that ingenol mebutate treatment led to gene expression changes in actinic keratoses, with complete lesion clearance in 40% of patients and identified genetic markers potentially predicting treatment response.

This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

This study found that the repressive histone mark H2AK119ub links inhibitory FGF signals with the quiescent state in hair follicle stem cells, revealing a signaling-epigenetic axis crucial for maintaining stem cell quiescence and tissue homeostasis.

In this study, altering the photoperiod in goats increased hormone concentrations and improved hair follicle development and skin antioxidant capacity, suggesting that short photoperiods may create favorable conditions for cashmere growth.

This study found that basal cell carcinoma exhibits patterns of hair follicle differentiation but is stuck in telogen arrest, which can be rescued by adding noggin and TGF-β2 in vitro.

This study reports that GLP-1 receptors and proglucagon are expressed in the skin of newborn mice, with GLP-1 potentially playing a role in skin development and hair follicle formation.

This study highlights the role of Orai1 in ameloblast differentiation and maturation, showing that its down-regulation affects cell proliferation and enamel formation during tooth development.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This study identified a novel recessive mutation in mice causing lethal congenital lamellar ichthyosis, with skin and hair follicle alterations similar to human congenital ichthyoses, linked to a specific genetic defect affecting Fatp4.

This review discusses epigenetic mechanisms in tissue repair across species and summarizes recent CRISPR-based technologies as promising tools for studying and enhancing tissue regeneration, but reports no new experimental results.

This book compiles papers from a 1988 symposium on human hair follicle research, highlighting collaboration between dermatology and industry, but reports no new clinical findings.

This review covers cell transplantation methods for genitourinary reconstruction, discussing tissue sources and complications but presenting no new clinical findings.

This review summarizes the role of G-protein-coupled receptors in wound healing and reports no new clinical results, highlighting their importance in signaling pathways and recent discoveries in their functions.

This study suggests that epidermal turnover could be a regulated mechanism of iron excretion, with systemic iron levels influencing keratinocyte behavior and differentiation markers in the skin.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This research observed that translation initiation shifts from cap-dependent to IRES-mediated pathways varied across tissues and cell types under stress and differentiation conditions in mice, with low IRES/Cap ratios signaling high stemness and potential multipotency, mediated by the RNA processing protein PTBP1.

This study found that dedifferentiated corneal epithelial cells can revert to a stem-cell-like state, aiding tissue homeostasis and repair, with this plasticity limited to the epithelial lineage and enhanced by niche-derived cytokines.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that mature dermal adipocytes have high plasticity, undergoing dedifferentiation and redifferentiation, which plays a significant role in hair cycling and wound healing.
