This article reviews the complex pathophysiology of polycystic ovary syndrome, highlighting how genetic, hormonal, and environmental factors contribute to its diverse symptoms, and reports no new results.

This scoping review found that while some small human pilot trials of extracellular vesicles as therapeutics showed promising outcomes, variability in study design and lack of placebo controls limit definitive conclusions about their safety and efficacy.

This review discusses what is known about the pathobiology of frontal fibrosing alopecia and reports no new clinical findings, highlighting potential environmental and genetic factors in disease pathogenesis.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

In this study, the combination of arsenic toxicity and hypoxia in Arabidopsis thaliana altered root development through stress-specific root growth phenotypes and changes in phosphate starvation response, energy metabolism, and redox signaling.

In this study, researchers reviewed the progress and challenges in using hydrogels for 3D printing in biomedical applications, highlighting advancements in structural complexity, and identifying ongoing issues like resolution improvement, cell viability, and ethical concerns for clinical use.

This systematic review investigated colchicine as a potential treatment for various skin conditions, finding that most studies reported generally positive clinical outcomes when used alone or with other drugs, despite some variability in results.

This study identified a severe MBTPS2 gene mutation in a Japanese patient with IFAP syndrome, suggesting other factors may influence the varied clinical severity of the condition.

This study reports a unique case of common variable immunodeficiency with autoimmunity linked to a heterozygous S250C variant in the autoimmune regulator gene, suggesting a potential molecular basis for this combination.

This review compiles EV proteomics data and reports that while MSC-derived EVs show promise in skin therapeutics, variability in protein cargo highlights the need for standardized methodologies in understanding process impacts.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

This review explores the eggshell matrix as a potential sustainable and cost-effective alternative source for glycosaminoglycans, but highlights the need for further research to enhance extraction techniques and economic viability.

This study examined genetic risk factors for alopecia areata in the Jordanian population but found no significant association between the 21 targeted risk loci and the condition, emphasizing variability in genetic predisposition across ethnic groups and potential non-genetic triggers.

This chapter reviews the use of electrospun matrices in creating tissue-engineered skin substitutes and reports no new clinical results; it emphasizes the need for a cell-friendly microenvironment.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

This review highlights the potential of drug-loaded extracellular vesicles as a promising drug delivery platform but notes that clinical translation faces challenges due to variability in methods and the need for standardization and safety evaluation.

This study suggests that elevated levels of IL-17A and IL-23 in alopecia areata may play roles in disease severity and activity, providing insights into potential therapeutic targets.

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.

In this review, researchers explored hair as a promising tool for identifying biomarkers in schizophrenia, highlighting its potential for supporting personalized medicine through ease of sampling, though acknowledging challenges like individual variability and methodological inconsistencies.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This review discusses the senescence–stemness connection in cellular biology and reports no new findings, highlighting implications for both tissue repair and aggressive cancer behavior.

This study found that intermittent treatment with FTI lonafarnib and sulforaphane may be a promising therapeutic approach for children with Hutchinson-Gilford progeria syndrome, as it improved the cellular phenotype.

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

This study reported that molecules from Zebrafish embryo cell differentiation can counteract neurodegeneration, regenerate tissues, and potentially reverse hair follicle damage in androgenetic alopecia.

This study found that cilostazol promoted hair growth in human dermal papilla cells and mouse models, suggesting its potential as a therapeutic target for alopecia treatment.

This study found that platelet-rich plasma might support brain health by enhancing glial cell function and modulating immune responses in inflammation, indicating potential as a treatment for brain disorders.

This study evaluated a novel hand-held low-level light therapy device for treating mild-to-moderate acne, finding it significantly reduced inflammatory lesions and moderate acne severity without severe adverse reactions, while also reducing Cutibacterium acnes viability in vitro.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.
