Zebrafish skin regeneration relies on cell behaviors and reactive oxygen species, with antioxidants reducing and hydrogen peroxide increasing regeneration.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

In this study, hair follicle germs containing vascular endothelial cells showed improved hair regeneration and morphogenesis-related gene expression in mice, suggesting a promising strategy for hair regenerative medicine.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This study in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

This study found that Wnt5a regulates hair follicle differentiation in mice by mediating epithelial-mesenchymal interactions and influencing dermal papilla cell activities.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study found that combining a human acellular amniotic membrane with iPSC-derived epithelial stem cells effectively repaired skin defects and promoted hair follicle formation in nude mice.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

This review discusses the plasticity of epithelial stem cells in regenerative contexts and reports no new research findings; the authors highlight potential implications for regenerative medicine and cancer.

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 study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

This study found that T cytokeratins appear more gradually and with complex coexpression patterns in developing nail structures compared to the more abrupt transition in hair follicles.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This review discusses the cosmetic applications of platelet-rich plasma in dermatology, highlighting its potential benefits and the need for more controlled studies.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This study found that the zinc transporter ZIP10 is crucial for epidermal development, as it influences the activity of p63, promoting epidermal morphogenesis.

This review discusses challenges in treating CMO associated with uveitis and highlights the need for prospective studies to guide therapy, as current treatments are largely empirical and potentially harmful.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

This study indicates that nail-matrical fibroblasts can induce hard keratin expression in non-nail-matrical keratinocytes, suggesting potential for using non-nail-matrical epidermal grafts to treat nail injuries.

This study found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.
