This study found that non-thermal atmospheric pressure plasma may stimulate hair growth through activation of the Wnt/β-catenin signaling pathway, suggesting it could be a potential non-pharmacological treatment for alopecia.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This study suggests that Keratin 15 expression in stratified epithelia may be regulated by two distinct mechanisms involving PKC/AP-1 pathway for differentiation and FOXM1 for basal cells, challenging its reliability as a sole stem cell marker.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This study identified the Hairless (Hr) gene-encoded protein as a corepressor that plays a crucial role in maintaining skin and hair by regulating epithelial stem cell differentiation and gene expression via chromatin remodeling, which may impact both development and disease.

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

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 maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

This study found that topical application of partial proteasomal inhibitors accelerates hair growth by stabilizing β-catenin and disrupting the hair cycle's normal balance of activation and quiescence.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study explored the molecular communication between hair matrix cells and dermal papilla cells in cashmere goats, revealing key ligand-receptor pairs and signaling pathways that facilitate intercellular crosstalk and potentially influence hair growth mechanisms.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.

In this study, Gsdma1/2/3 knockout mice showed reduced epidermal hyperplasia and inflammation when induced by PMA, which was attributed to decreased EGFR-Stat3/Akt signaling due to a decrease in related ligands.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This review highlights the emerging role of long non-coding RNAs (lncRNAs) in dermatology, suggesting that lncRNAs significantly impact signaling pathways involved in normal skin functions and skin diseases, offering potential as biomarkers and therapeutic targets.

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.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

This review discusses the formation and maintenance of hair follicles through dynamic cellular changes and signaling pathways, presenting a comprehensive overview but providing no new experimental findings.

This review discusses the role of vitamin D receptor signaling in hair follicle biology for alopecia treatment and underscores the need for continued research, without presenting new clinical results.
