This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

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 suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study found that AR/VDR-targeted agonist hormone therapy can inhibit cell viability in HR2-av triple-negative breast cancer cell lines through multiple mechanisms and may enhance the effects of chemotherapy.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

In this study, a newly developed nanoparticle-loaded hydrogel wound dressing demonstrated significant antibacterial, antioxidant, anti-inflammatory, and proangiogenic activities, effectively reducing pain and promoting healing in a murine burn wound model while preventing infection by *Staphylococcus aureus*.

This study identified the AtPRPL1 gene in Arabidopsis thaliana as being involved in cell elongation processes, despite unclear changes in cell wall composition from its altered expression.

This study found that collagen VI influences hair follicle growth and wound-induced regrowth by activating the Wnt/β-catenin signaling pathway in mice, suggesting potential therapeutic targets for hair loss.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no new experimental results.

This study found that inhibiting the enzyme 5α-reductase with finasteride counteracted stress-induced prepulse inhibition deficits in socially isolated rats by altering neuroactive steroid concentrations in the brain.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

This study found that finasteride impaired stress reactivity and reduced exploratory and impulsive behaviors in rats, potentially by altering the hypothalamus-pituitary-adrenal axis function.

This study found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

This study demonstrated that a new topical treatment using ketotifen-loaded microneedles, designed for prolonged release, significantly reduced inflammatory markers in an animal model of allergic conjunctivitis, suggesting enhanced therapeutic delivery and sustained ocular benefits.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study reported that Indian hedgehog (Ihh) signaling plays a crucial role in regulating tumor progression and metastasis in epithelial cancers, with Ihh deficiency leading to increased malignancy and metastasis in mice.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

DNA can predict physical traits like eye and hair color accurately, especially in Europeans, but predicting other traits and in diverse populations needs more research.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

This study reviews methods to ensure the reliability of machine learning models in medical imaging, focusing on bias detection, data drift assessment, and accuracy estimation without ground truth labels to enhance integration into clinical settings.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.
