This study identified four immune-related signaling molecules (LGR5, PTN, JAG1, and DKK1) associated with keloid, suggesting their potential role in its pathogenesis and as targets for new treatments.

In mouse models of alopecia areata, this study found increased dilation of lymphatic vessels in affected mice, with associated changes in gene expression related to vascular growth and immune cell movement.

This analysis concluded that mesenchymal stem cell-derived exosome therapy may offer a promising and safe approach for hair restoration, especially in androgenetic alopecia, despite limitations in study consistency and size.

This study provides a detailed analysis of cell subpopulations in a mouse model of wound-induced hair follicle regeneration, revealing specific cellular dynamics and heterogeneity that may influence hair follicle neogenesis.

This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.

This article provides a detailed analysis of immunosuppressive medications in transplant patients and discusses the increased risk of skin cancer, but it reports no new experimental results.

This study found that a single dose of TRP significantly reduced the number of UV-B-induced actinic keratosis lesions in a mouse model and was associated with improved skin histology and minimal side effects.

In a single case study, researchers reported increased hair density using a trypsin-isolated cell suspension containing CD34 and CD200 positive cells for treating grade III androgenetic alopecia.

This study reported that a single local subcutaneous infusion of mesenchymal stromal cells from the human umbilical cord promoted wound healing, improved blood circulation, and reduced wound size in patients with chronic wounds without significant adverse effects over one year.

This study found that human dermal stem/progenitor cells demonstrated greater proliferation and differentiation potential than hair follicle dermal papilla cells, which showed increased expression of hair regeneration markers.

This review discusses five genetic fate mapping methods used to study cell behaviors during development and regeneration, detailing the necessary tools and considerations without reporting new experimental results.

This study found that IL-18 rs187238 and rs1946518 single nucleotide polymorphisms were associated with increased susceptibility to alopecia areata in a Turkish population.

This study reviewed 39 studies with 3204 patients to identify characteristic trichoscopic findings in alopecia areata, highlighting yellow and black dots, broken, short vellus, and tapering hairs as key indicators. It found no single diagnostic trichoscopic finding but observed trichoscopy's utility in monitoring treatment response.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

This study found that a cell therapy product, RCS-01, was well tolerated in aged skin and led to significant increases in gene expression related to extracellular matrix homeostasis, although the small cohort size limited further efficacy analysis.

This study found genetic variations, including de novo variants and copy number variations, that may be associated with phenotypic discordance in monozygotic twins with various clinical conditions.

This review reports that the treatment of androgenetic alopecia is shifting from single therapies to personalized, multimodal approaches incorporating both traditional and emerging pharmacologics, regenerative strategies, nutraceuticals, cosmeceuticals, and device-based interventions, with combination regimens showing improved outcomes.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review explores recent advancements in precise cell manipulation technologies, detailing the status, principles, benefits, limitations, and future potential of methods like single-cell manipulation and 3D bioprinting for cells and tissue engineering.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study from Turkey observed that the COVID-19 pandemic adversely affected dermatology patients, particularly by interrupting treatments and restricting outpatient visits.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study suggests that human DSCCs may aid in hair follicle regeneration and reduce microinflammation, with potential applications in regenerative medicine evaluated through a new morphometric analysis.

This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

In a comparative genomic study, researchers observed significant genetic differences among the three chemical races of the alga Botryococcus braunii, leading them to propose reclassifying these races as distinct species based on their unique genomic characteristics.

The letter argues that blaming synthetic hair implants for scalp cancer based on one report is biased and possibly coincidental.

This study found that nestin-expressing hair follicle-derived cells express higher levels of certain neurotrophic factors and neural markers, indicating potential for neuroregenerative therapy applications.

This study evaluated the efficacy of various skin graft types for burn injury healing, finding that xenografts had the highest repigmentation rate (87.50%), while device-facilitated autologous skin cell transplantation showed outstanding efficacy in reepithelialization, highlighting its potential in clinical practice.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.
