This review discusses methods for generating induced pluripotent stem cells and highlights their recent applications in studying and treating COVID-19, but it reports no new experimental results.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

In this study, TC-1 cells, resembling stromal cells formed by epithelial-mesenchymal transition, significantly affected the behavior of normal human keratinocytes, supporting the role of stromal cells in tumor progression.

This study found that irisin, a myokine, increases hair growth by activating the Wnt/β-catenin pathway, enhancing cell proliferation and hair shaft elongation in both human cell and mouse models.

This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.

This review summarizes recent insights into corneal limbal stem cell differentiation and the potential role of progenitor-like cells, but reports no new experimental results.

In this article, researchers link menopause to hair follicle lifecycle changes, noting that estrogen decline, metabolic shifts, genetics, and stress can contribute to hair thinning and texture variation, although effects differ among women.

This study utilized a pigmented human epidermal equivalent model to incorporate melanocytes into the epidermis and found enhanced differentiation potential compared to conventional in vitro systems, reflecting in vivo cellular trajectories and highlighting melanocyte-to-keratinocyte communication pathways.

This study suggests that extracellular vesicles from prostate cancer cells could aid in identifying tumor heterogeneity and serve as biomarkers, while also playing a role in SARS-CoV-2 infection in nasopharyngeal mucus.

This study presents evidence that hair matrix progenitors and the enzyme Stearoyl CoA Desaturase 1 may play a role in maintaining the dermal papilla niche via autocrine Wnt and paracrine Hedgehog signaling in mice.

This article discusses the various administration methods and considerations for testosterone replacement therapy, highlighting the importance of individualized therapeutic monitoring and potential adverse effects, but reports no new clinical results.

This study found that gels containing glycyrrhizic acid and aqueous Glycyrrhiza glabra extract significantly reduced underarm hair growth in terms of area, thickness, length, and number compared to their gel bases.

This study found that in live mouse epidermal stem cells, chromatin compaction is heterogenous and reflects differentiation status, with transcriptional changes largely preceding chromatin rearrangements during differentiation.

This article discusses male pattern alopecia and current hair replacement surgical techniques, without presenting new clinical findings.

This review summarizes research on androgens' roles in female reproductive function, noting their impact on IVF outcomes and the development of PCOS, and highlights the need for mechanism-based therapies.

This study evaluated a new collagen and tannic acid hydrogel in rat liver and heart bleeding models, finding it reduced blood loss and hemostatic time compared to commercial products, with benefits such as enhanced biodegradability and potential for clinical use.

This study found that the Yangyin Qingre Huoxue Prescription effectively reduced the progression of atherosclerosis in mice, with lipid-regulating and anti-inflammatory functions and lower hepatotoxicity than simvastatin.

This study explored the Belanger tradition, a Sasak hair-cleansing ritual using natural ingredients, and concluded that it combines cultural heritage with sustainable practices and scientifically supported benefits.

This study concludes that the Greek version of the Dysmorphic Concern Questionnaire is a reliable and valid tool for assessing body dysmorphic disorder-related concerns in both research and clinical settings.

In this study, researchers used transcriptome sequencing and bioinformatics analysis to identify important genes and pathways involved in the transition between hair growth phases, offering new insights into hair follicle cycle regulation and development.

This review highlights the current progress and application pros and cons of various cell-based screening platforms in drug discovery, discussing challenges and potential improvements for these innovative methods.

Disulfide bonds are crucial for hair structure during keratinization.

In this study, deleting the Igf1 receptor in specific skin cells of mice affected hair follicle cycling but not overall skin health, suggesting Igf1r's role in hair cycle regulation through Bmp-4 activation.

This study found that exosomes derived from bovine colostrum promoted hair growth in mice by activating the Wnt/β-catenin pathway, with effects similar to minoxidil but without adverse effects.

In this study, researchers developed an LC-MS/MS method to accurately quantify cortisone and cortisol levels in human scalp hair, finding that concentrations decrease predictably along the hair shaft, which could assist in identifying abnormal glucocorticoid exposure.

This study successfully established and validated a method using LC-MS/MS to measure multiple androgens in plasma, finding that individuals with acne had higher levels of certain androgens compared to those with obesity.

This review examines platelet-rich plasma therapy's multidisciplinary applications in regenerative medicine and discusses preparation challenges but presents no new clinical results.

This study found that regardless of alopecia type, follicular unit extraction resulted in good patient satisfaction concerning appearance and visual age.

This study found that human progenitor keratinocytes form unique complements of enhancers and super-enhancers during differentiation and migration, influencing gene expression and skin disease variant enrichment.

This review discusses the biology and signaling mechanisms of dermal papilla cells in hair follicle growth and reports no new clinical results; the authors emphasize the importance of optimizing culture conditions for hair restoration.
