Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This review discusses the role of circadian rhythms in stem cell differentiation and tissue regeneration, emphasizing their impact on organ physiology and aging, but reports no new experimental results.

This review discusses the role of miRNA/mRNA regulatory networks in skin development, epidermal homeostasis, and tissue remodeling, and suggests potential for miRNA-based therapies in treating skin conditions, but reports no new clinical results.

This study found that differences in cashmere fiber diameter in Tibetan cashmere goats are associated with variations in metabolic, hypoxic, and stress response-related proteins, offering insights for breeding strategies.

This study examined noninvasive tissue samples, including buccal swabs, hair follicles, saliva, and urine cell pellets, and found hair follicles and urine cell pellets promising for transcriptomic and clinical analyses due to their sample quality and performance in disease-relevant applications.

This study found that lncRNA-599547 positively regulates the expression of the Wnt10b gene by interacting with miR-15b-5p, enhancing the inductive property of dermal papilla cells in cashmere goats.

This study demonstrated that skin organoids derived from human stem cells can model cutaneous tuberculosis, revealing that fibrosis development in Mycobacterium tuberculosis-infected organoids is linked to the PI3K-AKT and AP1 pathways in fibroblasts, and suggesting the potential for antifibrotic treatment evaluation.

This study found that the protein Foxn1 is crucial for the development and fat-storing capacity of dermal white adipose tissue in mice, influencing both lipid metabolism and adipogenesis in the skin through Bmp2 and Igf2 signaling pathways.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

This study found that regulatory sequences crucial for inducing K6a expression in response to epidermal injury are located in specific upstream regions of the K6a gene in transgenic mice.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

This study found that retinoic acid induces epidermal transdifferentiation into mucosal epithelium in both chick and mammalian embryonic skin, involving specific gene expressions and pathways.

Alopecia areata involves complex immune cell interactions, especially between CD8+ T cells and macrophages, which could help develop new treatments.

This study found that adding cell adhesion-linked gene expression variables improved the identification of patients with SLN metastases within 90 days of melanoma diagnosis compared to using clinicopathologic variables alone.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

In this research, LEF1 was identified as a crucial transcription factor for submucosal gland development in mouse and ferret tracheas, though it requires other factors to induce gland formation.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

In this study, K19-lacZ transgenic mice exhibited epithelial-specific reporter gene expression in tissues such as the pancreas and stomach, suggesting the K19 promoter is a valuable tool for studying epithelial cell biology.

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

This study identified a wide range of differentially expressed lncRNAs and mRNAs in the hair follicles of Hetian sheep, which may be useful for further research on improving carpet wool quality.

This study identified polymorphisms in HGT-KRTAP7-1 and KRTAP8-1 genes in Argentine llamas that may impact fiber characteristics by altering amino acid residues critical for keratin-associated protein properties.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

A rare genetic deletion in the KRT1 gene causes unique skin symptoms in a family.

This study found that deleting Snai2 and Snai3 genes in mice disrupts immune cell development, resulting in severe autoimmunity and early death due to the loss of immune tolerance.

This study found that mesenchymal cells from different organs exhibit substantial heterogeneity, with thymic mesenchymal cells particularly adapted for interacting with epithelial and hematolymphoid cells in high-apoptosis environments.
