Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This review summarizes physiologic skin changes during pregnancy and specific pregnancy-related dermatoses but reports no new clinical results.

This study found that mice lacking REDD1 experienced an expansion of dermal white adipose tissue through both hypertrophy and hyperplasia, suggesting a potential therapeutic target for skin adipogenesis regulation.

This study in mice found that fractional photothermolysis can improve dermal scar formation by promoting slow, organized collagen regeneration with minimal myofibroblast activation.

This review discusses the conditions, genetic factors, and treatment options related to polycystic ovary syndrome, but reports no new clinical findings, emphasizing the need for future research.

This study found that Polygoni Multiflori Radix (PMR) reduced collagenase and elastase activity after UVB damage in fibroblasts, suggesting potential anti-aging properties for cosmetic use.

This review examines the mechanisms of lung fluid imbalance in COVID-19-related pulmonary edema and suggests potential drug targets to improve management and reduce mortality.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This review explores the cellular and molecular basis of wound-induced hair neogenesis and its relationship with aging but does not report new clinical results, highlighting areas for future research.

This study found that flower extracts of Wedelia trilobata may serve as a promising active ingredient for cosmeceutical products due to their antioxidant, anti-inflammatory, and antimicrobial properties.

The document explains what healthy skin, nails, and hair look like on an ultrasound.

This review found that hydrolyzed collagen supplementation, particularly marine collagen, improves skin hydration, elasticity, and density while strengthening hair and nails, especially when paired with vitamin C and trace elements; however, more studies are necessary to evaluate long-term efficacy across different sources and demographics.

This Ph.D. project aims to evaluate the self-assembling potential of hair keratin extracts and study the cellular response to both crude and purified keratins, highlighting their potential applications from biomedical to water remediation.

This review explores the skin regeneration process in spiny mice and highlights differences from laboratory mice, focusing on potential molecular and immune system roles without reporting new experimental results.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

This study analyzed 853 articles to reveal that research on silica-based nanobiomaterials in regenerative medicine has rapidly increased, with distinct regional differences in impact and emerging focus areas in drug delivery and wound healing.

In this study, low-dose oral minoxidil was found to have a favorable safety profile for treating alopecia, with mostly mild side effects, in both general and hypertensive populations.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

In this study, researchers found that the expression of laminin, collagen type IV, and fibronectin in fetal human skin begins in hair follicle germs and extends to epidermal cells by 21 weeks gestational age.

In this study, BTP-loaded solid lipid nanoparticles were developed and shown to protect hair from heat-induced damage by enhancing cuticle integrity and thermal resistance in simulated thermal straightening conditions.

In this study, researchers found that non-invasive analysis of skin surface lipid RNAs revealed alterations in gene expression patterns associated with atopic dermatitis, suggesting its potential for understanding skin disease pathophysiology.

The document honored Yvonne, announced upcoming dermatology events, and introduced new journal editors.

In this study, researchers found that a composition containing mannose-6-phosphate significantly reduced the total skin pore area by 24% in women after 56 days and by 30.2% in men after 7 days, suggesting its effectiveness in improving pore appearance by targeting dermal and epidermal modifications.

This study reported that the Biofibre® hair implantation system, used on 1,518 patients with various degrees of baldness and causes of alopecia, delivered immediate and visible results without scarring or hospitalization, which greatly improved patients' self-esteem and psychological well-being.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.
