This chapter provides an overview of skin physiology, aging effects, and how environmental factors like UV damage impact skin health, without presenting new research findings.

In this study, researchers overexpressed Lrig3 in mouse skin and observed hair loss linked to changes in skin protein profiles and signaling pathways, suggesting a potential role for Lrig3 in maintaining skin homeostasis.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

This study observed that activin A and its antagonist follistatin influence the differentiation of inner ear hair cells by regulating the expression of the transcription factor ATOH1.

This study found that knock-down of keratin 15 in various cell lines affected cell spreading, morphology, migration, differentiation, and proliferation, suggesting its role in maintaining the stem cell nature of keratinocytes.

This study developed HA-gel-dex hydrogels with enhanced ECM-like properties and functionality, showing promise for 3D bioprinting, tissue repair, and as wound dressings due to improved cell interaction, cytocompatibility, antimicrobial synergy, and wound healing in mice compared to traditional ECM bio-inks.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

This review highlights the need for methodologies to understand and quantify drug penetration into hair follicles as significant drug pathways, noting this area lacks comprehensive articles and reports no new results.

This study observed that mature neutrophils and their extracellular traps inhibit wound-induced hair follicle neogenesis in mice, despite being stimulated by pro-regenerative cues.

This study found that skin surface lipids contain measurable mRNAs, providing a non-invasive way to study skin diseases, with specific gene expression changes observed in atopic dermatitis patients.
