This study found that high skin expression of amphiregulin in acute graft-versus-host disease was associated with severe disease grade, poor overall survival, and increased non-relapse mortality.

This review outlines the role of mechanical forces in the development of sensory organs like eyes and ears, emphasizing insights from recent animal studies and microfabricated organoid systems; it presents no new experimental results.

In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.

This study found that bursts of ERK activation in the epidermis of mice were linked to cell division, supporting synchronized cell proliferation and transient ERK activity in living tissues.

This article discusses how the brain's neural circuits evaluate skin aging to judge social standing and suggests that people often attempt to deceive themselves and others about their true age.

This study used confocal Brillouin microscopy to observe that a decrease in tissue compressibility occurs during the development and regeneration of axolotl limbs, suggesting mechanical changes linked to regeneration stages undetectable by fluorescence microscopy.

This study suggests that human skin contains distinct fibroblast subsets with unique expression profiles and functions, which can be isolated to investigate their role in skin pathogenesis.

This study used transgenic mice to show that disrupting TGF-β signaling in K14+ progenitor cells led to increased stem cell proliferation in the tongue.

This study found that variations in mouse skin thickness, influenced by gender and hair growth cycles, significantly affect optical scattering measurements, which are important for developing biomedical optics techniques.

This study found that a human relevant potency threshold for estrogen receptor alpha agonism may serve as a health-protective screening tool, and highlights inference performance as essential for scientific confidence frameworks.

In this study, the researchers found that optic atrophy 1 (OPA1) is involved in the transition between filamentous and rounded mitochondria in hair follicle dermal papilla cells, potentially influencing cellular energy dynamics.

This study suggests that phenotypic plasticity, including processes like dedifferentiation and transdifferentiation, plays a crucial role in cancer initiation, progression, and therapy resistance, broadening our understanding of cancer dynamics and potential treatment strategies.

This study observed that among !Kung San males, adult androgen levels, particularly DHT, were negatively associated with indicators of fluctuating and directional asymmetry, suggesting a link to phenotype quality.

This study found that gaze duration in a social evaluation task was linked to mental health outcomes in trans men, trans women, and cisgender women more than six months later.

This study found that using polarized magnification during hair transplant procedures may ease recipient site creation and reduce transection of existing hair follicles, potentially maximizing hair density.

This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

This study found that the activation of ER‑β increased keratinocyte proliferation and gene expression related to epidermal regeneration, enhancing wound healing in both cell models and rats.

This review suggests that most mutations in the SRD5A2 gene show no clear genotype-phenotype correlation in 5-α-Reductase deficiency, although mutation location affects severity.

In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

This study developed a leakage-resistant machine learning framework for classifying hair loss types, emphasizing transparency through explainable AI. Among tested models, Extreme Gradient Boosting excelled, achieving high accuracy and stability on both cross-validation and holdout datasets.

This source provides procedural details without reporting new experimental findings or conclusions.

In this study, researchers developed a machine learning model that accurately diagnosed scalp conditions like fine dandruff and perifollicular erythema with 75% and 82% accuracy, respectively, and created a user-friendly web platform for scalp health self-assessment, which achieved high user satisfaction.

This review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

This study found that carefully engineered hydrogels and asymmetric morphogen gradients facilitated the formation of anatomically relevant skin organoids from iPSC-derived EBs, improving pigmentation and hair follicle generation.

In this study, researchers used a murine model of irritant contact dermatitis to reveal that hair follicle regions serve as key sites for neutrophil transepidermal migration, which requires MMP-9 expression stimulated by dermal monocytes.

This narrative review proposes the concept of "repigmentation competence" for vitiligo lesions, suggesting that therapy responses are influenced by lesion-specific biological factors related to immune, regenerative, regulatory, and microenvironmental processes, and highlights the emerging role of combination therapies targeting these pathways.

This review summarizes recent findings about the multi-site differentiation of tissue regulatory T cells, emphasizing the pivotal role of epigenetic remodeling, but it reports no new clinical results.

In this study, researchers identified the PLD-mGluR protein in primary mechanosensory terminals as the homomeric GluK2 kainate receptor, functioning purely metabotropically, which is suggested to be common to various sensory endings.

This study found that transgenic mice expressing cgVEGF164 had increased hair follicle diameter and density, potentially linked to higher phosphorylation levels of ERK1/2, AKT1, and LEF1 proteins.
