This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

People with hair loss have more androgen receptors and enzymes in certain follicles, with men and women showing different patterns.

This review explores various theories of colorectal cancer stem cell biology and highlights the need for better identification and targeting of these cells to advance treatment strategies, but reports no new clinical findings.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This article discusses the treatment of androgenetic alopecia and alopecia areata with finasteride and minoxidil but reports no new clinical results.

This review discusses the potential benefits of myo-inositol supplementation for insulin resistance-related disorders and diabetic complications, but reports no new clinical results.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

This study reports that progressive frontal fibrosing alopecia, a distinct and gradually stabilizing form of lichen planopilaris affecting elderly women and often involving eyebrow hair loss, lacks effective treatments.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study suggests that increased use of anticancer drugs from 2004 to 2008 has led to higher environmental release, necessitating expanded monitoring and research on their ecotoxicological impacts.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

This review examines the immunological aspects of alopecia areata, focusing on genetic, neuroimmunological, and immune privilege factors, but does not report new clinical findings.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study found that TRPA1-deficient mice exhibited normal cold sensitivity but had decreased mechanical response in nociceptors, suggesting TRPA1's role in mechanotransduction.

This review discusses guidelines for androgen use in women and concludes that more research is needed before recommending testosterone due to insufficient evidence on safety and efficacy.

This review elaborates on the skin side effects of chemotherapy and emphasizes identifying and managing both common and life-threatening skin reactions, without presenting new clinical findings.

This article discusses evaluation and treatment options for a 19-year-old woman with slowly progressive hair growth and reports no new clinical findings.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

In this study, the prevalence of polycystic ovary syndrome among Han Chinese women aged 19-45 was found to be 5.6%, and PCOS was associated with increased metabolic risks, particularly in obese individuals.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

This study found that Wnt1/βcatenin signaling plays a crucial role in activating the epicardium and cardiac fibroblasts, which supports cardiac repair following acute ischemic injury.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.
