This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review discusses the International Evidence-Based PCOS Guidelines, which aim to improve diagnosis and management of PCOS and its associated comorbidities, noting the importance of early intervention and healthy lifestyle changes; it reports no new results.

This study found that PBX1 enhances the proliferation and reprogramming of hair follicle mesenchymal stem cells by activating the AKT/GSK3β signaling pathway, promoting NANOG expression, and inhibiting apoptosis.

The researchers reported that in Arabidopsis collet hairs, nuclear positioning near the cell tip is not essential for hair growth, although it correlates with growth dynamics.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

In this study, extracts from three Polynesian plants—Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana—were found to increase dermal papilla cell proliferation and modulate hair growth-related gene expression, suggesting potential for stimulating hair growth.

This study introduced Cadd4, a peptide-based degrader developed using computer-aided drug design, which effectively reduced PCSK9 levels and increased LDL receptor expression, resulting in decreased plasma cholesterol and LDL-C levels in hypercholesterolemic mice, without liver toxicity.

This study found that deleting the Mof gene in mouse skin leads to severe defects in skin cell self-renewal, differentiation, and hair follicle growth, indicating that MOF is crucial for mitochondrial and ciliary gene expression and essential for skin development.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

This study highlights factors contributing to increasing seborrheic alopecia among teenagers, including hormonal, lifestyle, and psychological influences, and suggests integrated treatment strategies including medication, lifestyle adjustments, and psychological interventions.

This study discusses the need for better organization and specialized services in Alzheimer's prevention, focusing on modifiable factors like hearing impairment, vascular risk, and lifestyle habits, and highlights challenges and opportunities from the two-year experience of Brain Health services at Karolinska Institutet in Sweden.

This study explores the role of antidiabetic medications, particularly metformin, GLP-1 receptor agonists, and DPP-4 inhibitors, in managing PCOS, highlighting their combination with hormonal therapies and lifestyle interventions for a comprehensive treatment approach.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This narrative review discusses expert consensus on the optimal use of botulinum toxin injections for cosmetic applications in facial and oral-maxillofacial areas across Asian and Caucasian populations, highlighting injection techniques, effective doses, historical context, and potential complications.

This study found that calcium and all-trans retinoic acid affect the proliferation and differentiation of goat hair matrix cells, which are essential for cashmere growth research.

This study identified key mRNAs and lncRNAs, along with related pathways, that play potentially important roles in hair follicle development and cycling in cashmere goats.

This study demonstrates a method using intravital imaging to observe sensory hair-cell development and regeneration in zebrafish, which may facilitate assays for drug discovery related to aural function preservation.

In this study, procerus and corrugator myectomy techniques during browlifts significantly improved dynamic glabellar wrinkles compared to browlifts without muscle resection over 12 months.

In this study, researchers identified key miRNAs and target genes involved in hair follicle development in Merino sheep, providing insights that could aid in improving sheep breeding for wool quality.

This study reported that a novel cationic liposome formulation for delivering encapsulated Cas9 protein and sgRNA successfully decreased SRD5α2 mRNA expression by 29.7% in vitro, suggesting a potential alternative treatment option for conditions like prostate cancer and benign prostatic hyperplasia without current drug side effects.

This study identifies specific molecular components involved in the intracellular trafficking of LGR5, revealing mechanisms that differ from typical GPCR recycling processes.

This study provides the first direct evidence that spermidine can stimulate hair growth and modulate human epithelial stem cell biology in cultured human hair follicles.

This study found that stage-specific epigenetic changes, particularly involving the gene PDGFC, may affect wool fiber development in Zhongwei goats, potentially serving as a biomarker for fur goat selection.

In this study by Sawada et al., the researchers developed a human striatal model using stem cells and postmortem samples, revealing accelerated neuronal maturation and specific gene expression changes linked to schizophrenia risk, which may inform future research on the disorder's developmental roots.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

This study found that FGF5 alternative spliceosomes inhibit dermal papilla cell proliferation and regulate hair follicle growth-related gene expression, impacting hair follicle development in rabbits.

RCS-01 is safe and may help rejuvenate aging skin.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This study highlights the potential of GPR30 and its selective agonists as promising therapeutic targets for treating hair loss disorders and conditions that respond to estrogen, emphasizing their role in modulating hair growth.
