This study shows that alpha 6 + /MHCI - cells have gene expression profiles similar to hair follicle stem cells, suggesting they may be enriched for stem cells.

Keratin proteins in epithelial cells are dynamic and crucial for cell processes and disease understanding.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This study suggests that the water fraction of Chrysanthemum zawadskii extract promotes hair growth by inducing telogen hair follicles in mice to enter the anagen phase and stimulating cell differentiation.

In this study, researchers observed that human sebaceous glands can regenerate in a mouse model using transplanted human skin, potentially offering a tool to study sebaceous gland biology and regeneration.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

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 identified various cell types in the canine claw, showing complex mechanisms of cellular differentiation similar to mammalian hair and human nails.

This letter reports no new findings and discusses potential concerns regarding 5-alpha reductase inhibitors on lung function, suggesting a reason for discontinuation during the COVID-19 pandemic.

This study introduced the concept of spatiotemporal clocks to understand how different phases of mammalian wound healing are coordinated, with a focus on the spatial domains and oscillatory molecular signals involved, while highlighting the potential for regenerative therapeutic strategies.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This article explains the significance of culturing the pilosebaceous unit for studying related diseases and skin epithelial stem cells, but it reports no new findings.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

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.

In this study with mice, simultaneous inactivation of Smad4 and PTEN genes led to rapid development of invasive forestomach squamous cell carcinomas, mirroring human esophageal SCCs.

In this study, the deletion of Smad4 and PTEN genes in mice was associated with rapid and invasive squamous cell carcinoma formation in the forestomach, modeling human esophageal cancer progression.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

This study suggests that 4-META resin may be more effective than cyanoacrylate for promoting wound healing in rats, as the wounds were covered by epithelial tissue faster with 4-META resin.

Wound healing is a complex process involving different cells and stages, leading to scar tissue formation and strength increase over time.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

This review discusses current and emerging treatments for benign prostatic hyperplasia and emphasizes the need for further research to optimize treatment selection, but reports no new clinical results.

This review addresses alopecia areata, emphasizing its autoimmune nature, unpredictable course, and lack of preventive or curative treatments, while noting standard and emerging therapies such as topical steroids and Janus kinase inhibitors.

This study demonstrates that using a K15 promoter-driven GFP labeling technique allows for the identification and characterization of epithelial stem cells in adult human hair follicles.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.
