This study evaluated a new AI-linked imaging device for grading dandruff severity, finding high correlation with expert assessments and suggesting its potential application in other skincare areas due to its versatility and ease of use.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

This study found that hair cortisol levels in black-tailed prairie dogs, influenced by factors like predation risk and lactation, were associated with reproductive success, supporting the Cort-Adaptation hypothesis.

This study found that changes in the expression of the Agouti gene contribute to the pale pigmentation in beach mice, with implications for melanocyte development and localization.

In this study, the elimination of NG2+ hair follicle stem cells during the anagen phase was associated with an aggravated sensitization phase of allergic contact dermatitis, suggesting their immunosuppressive role.

This study found that fibroblasts from Emery-Dreifuss muscular dystrophy patients with certain genetic mutations overexpress markers of fibrosis, and gene correction techniques reduced fibrogenic molecule expression in cell models, suggesting potential therapeutic applications.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This research presents the Dodatek A model, elaborating on androgen function through new mathematical indices and methodological improvements, shifting focus from serum hormone concentrations to system interactions to better describe androgen activity comprehensively.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This study observed significant differences in immune cell infiltration and gene expression across different skin sites, with the back displaying higher tolerance-promoting immune mechanisms, which may enhance epicutaneous immunotherapy outcomes.

This review discusses how stem and progenitor cells communicate to synchronize their differentiation responses, highlighting the challenges in identifying these mechanisms and surveying new technologies that may overcome these obstacles.

This paper reviews Dr. Norman Orentreich's original work on androgenetic alopecia and the principle of "donor dominance," without reporting new research results.

This paper describes the hGRα gene structure and its expression, focusing on the functional properties of the longest GRα isoform, but reports no new results.

Blocking EGFR in mice causes hair loss and skin changes.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

In this theoretical study, the authors developed a computational model to explore whether a reaction-diffusion process could explain the signal inducing axolotl spinal cord regeneration, proposing that regeneration control depends on cell sensitivity to the signal and its diffusion characteristics.

This study reports that fly blood progenitors in a long-term organ culture model undergo symmetric cell divisions influenced by cell size and orientation, with infection triggering changes in cell differentiation kinetics.

This study found that distinct neurons in the nucleus accumbens lateral shell regulate scratching behavior differently; D1R neurons promote scratching while D2R neurons help stop it, with elevated dopamine levels during chronic itch potentially enhancing persistent scratching.

This study found that ponytails with small fractions of gray hair have significantly lower swing height and higher damping, affecting the dynamic movement and appearance compared to those with fewer gray hairs.

This study developed a 3D computational model to simulate how skin, fat, and muscle deform under suction, reporting that as suction pressure increased, skin thickness decreased, while fat thickness increased, and muscle thickness remained stable, closely aligning with experimental results.

The KDM1 gene helps Venus flytraps close by managing potassium ions.

This study suggests that the 5α-reductase inhibitor finasteride modulates sensorimotor gating in rats by affecting D1 and D3 receptors, but not D2 receptors, with varying effects based on genetic strain.

In this theoretical study, axolotl spinal cord regeneration was modeled using a reaction-diffusion process, suggesting that the control of regenerative response relies on cell sensitivity to the signal and its diffusion characteristics, laying groundwork for identifying the signaling mechanism.

This study found that in participants with notalgia paresthetica, 8 weeks of treatment with difelikefalin significantly improved itch intensity and increased the rate of strict complete response compared to placebo, starting as early as week 3.

This study found that, in mice, different precursor populations give rise to Merkel cells in hairy versus glabrous skin, but their formation is controlled by a common genetic program involving FGFR2 signaling.

In this study, a deep neural network model called regX was developed to prioritize driver regulators for cell state transitions by incorporating gene-level regulation and interactions, showing potential therapeutic targets in type 2 diabetes and hair follicle development when applied to single-cell multi-omics data.

This study found that the transcription factor Meis2 regulates the maturation and innervation of sensory neurons in mice, affecting their response to light touch.
