In this study, researchers identified the ventral matrix as the primary source of nail plate formation, while the dorsal portion is generated by the apical matrix.

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 areola formation in mice requires a combination of pregnancy hormones and mechanical strain, with individual stimuli causing only modest changes in epidermal proliferation and connective tissue remodeling.

This study found that keratin expression patterns vary within nail unit structures, with the nail matrix uniquely expressing the acidic hair-type keratin Ha1.

This study found that in rats, combined treatment with finasteride and doxazosin altered epithelial cell behavior and matrix metalloproteinases activity, suggesting effects possibly mediated by TGF-β1 and androgen pathways.

This article reviews various recent studies and articles relevant to plastic surgeons, covering topics like alopecia treatment, wound therapy, breast implant safety, and surgical techniques, but provides no new clinical results; it aims to update readers on key developments in plastic surgery.

This article discusses how recent research suggests that aggressive video games have little effect on aggression and violence among players, calling for professional organizations to update their policy statements accordingly.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This review discusses the development and application of cell-derived matrices in regenerative medicine and disease modeling, presenting various fabrication techniques and future perspectives, but reports no new results.

This study found that epidermal stem cell-specific Jag1 expression levels are crucial for effective wound healing and scar reduction, and porcine acellular dermal matrix treatment enhances this process in mice by boosting Notch/Jagged1 signaling.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This review discusses the similarities between wound healing and embryonic development, focusing on signaling pathways and their potential for developing new wound healing strategies, and reports no new clinical results.

The hydrogel helps heal wounds without scars by releasing two drugs gradually.

The demineralized bone matrix scaffold is better for cell attachment than the mineralized bone allograft.

Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

This case report describes a 75-year-old woman with pustular psoriasis who developed Beau's lines on her nails, coinciding with episodes of telogen effluvium.

This study found that the Plcd3(mNab) mutation in mice worsens the alopecia caused by Plcd1 loss, suggesting synergistic effects between Plcd1 and Plcd3 on hair follicle health.

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.

In this study, collagen scaffolds functionalized with heparin and growth factors significantly enhanced long-term skin regeneration and growth in a sheep model of fetal skin defect, suggesting potential for prenatal spina bifida treatment.

This review discusses the roles of dermal white adipose tissue in skin functions and pathology, underscoring its antibacterial activity and potential anti-fibrotic role, but reports no new experimental results.

This review discusses the experimental targets of fetal wound healing and evaluates existing therapies for scarless healing in adult skin, but reports no new research findings.

In this review, the authors explored the diverse roles of fibroblasts in wound healing, suggesting that understanding their complexity could lead to better insights into wound pathologies and the development of new treatments.
