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 local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study suggests that variations in PCOS phenotypes observed across different ethnic groups may be due to a genetic gradient resulting from historical human migrations and genetic drift.

In this study, patient-reported outcomes indicated that greater weight loss with GLP-1RA treatments was associated with increased reports of adverse cosmetic effects such as skin laxity, facial volume loss, and hair shedding, despite improvements in some preexisting inflammatory skin conditions.

This study concluded that both low and incremental radiant exposures of diode lasers produced similar hair reduction and patient satisfaction, but low radiant exposure was less painful and better tolerated.

This article discusses the ergonomic challenges in hair restoration surgeries, particularly FUT and FUE techniques, emphasizing the need to minimize pain and fatigue for patients and surgeons, but it reports no new clinical results.

This study found that in mutant NRAS melanoma, MEK inhibitors led to increased AKT signaling and reduced MIG6, a change that may enhance cell migration and invasiveness.

The researchers developed a new follicular unit extraction system with adjustable needle lengths and precise rotation speed, which they report as being superior to existing systems for non-incisional hair transplants.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This study introduced a volar skin excisional wound model that closely mirrors human wound healing and supports evaluation of skin regeneration with multiple appendages and innervation.

This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

This study reveals that human hair follicles transition between active and dormant states stochastically, challenging the idea of a cyclical automaton controlling hair growth.

This study explored a mechanism for making Turing pattern formations more predictable and robust by isolating pattern modes to prevent their sensitivity to initial conditions, which can lead to different outcomes from minor initial changes.

This study found that in both rodents and humans, knee laxity increased at certain phases of the reproductive cycle due to sex-steroid influence, particularly under high levels of estrogen and progesterone.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study suggests that the HCR risk allele within the PSORS1 locus may contribute to psoriasis susceptibility by altering gene expression related to skin structure and differentiation, although these changes alone might not result in clinical symptoms.

The study reported a significant genotype–phenotype correlation in prepubescent males with XLHED, particularly in the severity of skin and hair manifestations between those with different EDA mutations.

In this study, researchers analyzed the occipital donor area for hair transplantation among men aged 50–55 with androgenetic alopecia and found that while most subjects met standard safe donor area criteria, individual variations suggest a conservative approach to donor area selection.

This study found that in mice, knockout of Rac1 and Rac3 in keratinocytes led to reduced white adipose tissue and revealed Rac-dependent paracrine pathways affecting pre-adipocyte differentiation.

This study found that in male androgenetic alopecia, the contrast enhanced phototrichogram technique was superior in detecting changes in hair density and thickness compared to other methods.

This study found that Wnt and Hedgehog signaling coordinate to create sharp cell type boundaries during hair follicle development by synchronizing cell cycle exit and differentiation.

This study reports that the maintenance and morphogenesis of skin appendages rely on both the dose and duration of ectodysplasin signaling.

In this study on Drosophila embryos, researchers observed that the Slit/Robo signaling pathway is crucial for the collective migration and proper positioning of Posterior Signaling Center cells within the hematopoietic niche, highlighting its role in niche assembly and cellular organization.

Certain substances can help skin cells become anti-inflammatory, aiding in tissue repair.

This study evaluated the learning curve for using the Hair Implanter Pen, finding it to be operator dependent.

This study found that the proposed Bayesian measurement-error-driven hidden Markov regression model effectively calibrated inflated covariate effect sizes in a community-based survey on androgenetic alopecia regardless of misclassification type.

This article provides no abstract or new findings and focuses on a patient registry related to spasticity care.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This study reports that improvements to the EczemaNet pipeline, incorporating pixel-level segmentation and data augmentation, enhanced the reliability and interpretability of assessing atopic dermatitis severity from digital images.

This study describes a novel FUE device that may perform successfully across various patient scenarios, adapting to differences in skin firmness, thickness, and hair curliness.
