In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

In this study, washing rhesus monkey hair with water or shampoo significantly reduced cortisol levels, suggesting potential underestimation of chronic stress hormone deposition in hair due to washing.

This study found that in lactating Holstein cows, hair from the tail switch, which grows faster and is more sensitive to cortisol changes, is ideal for measuring hair cortisol levels.

This study found that combining liraglutide with metformin led to greater weight loss and waist circumference reduction than either treatment alone in obese women with PCOS resistant to metformin monotherapy.

This study found that specific gene expressions during different stages of hair follicle development in Merino sheep are linked to wool-related traits, and may also be relevant to human skin, metabolic, and immune traits.

This study found that testosterone therapy in trans men increased facial and body hair growth while the prevalence and severity of acne peaked at 6 months but were primarily mild after long-term treatment.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This review discusses recent evidence on how night-shift work affects the circadian system, sleep, and alertness in shift workers, and reports no clinical results; potential impacts on health are considered.

This review explains the genetic diversity of sheep wool keratin-associated protein genes and explores how this variation might be leveraged for selective breeding to enhance wool fiber traits.

This study proposes a new, objective method to classify human hair into eight categories based on specific shape measurements, rather than traditional ethnicity-based classifications.

In this study, caffeine applied in a shampoo penetrated hair follicles faster and more effectively than through the skin surface within the first 20 minutes.

This study found that Polygonum multiflorum extract may promote hair growth by inducing the anagen phase in the resting hair follicles of mice.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

This report describes a case of acute liver injury in a woman following the use of Shen-Min, a herbal hair growth supplement, highlighting a potential link to acute hepatitis.

This study found that disrupting the Sox21 gene in mice led to progressive hair loss and regrowth, identifying Sox21 as a key regulator of hair shaft cuticle differentiation.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This study suggests that short telomeres may produce similar aging-related symptoms across different segmental progeroid syndromes, offering potential insights into normative aging processes.

This article reviews the development and formulation of shampoos, emphasizing their dual role as cosmetic and medicinal products, but presents no new experimental findings.

This case report describes acute liver injury in a 5-year-old Caucasian girl after ingesting the Chinese herbal product Shou-Wu-Pian, suggesting a potential link between this unregulated herbal remedy and hepatotoxicity.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

This study mapped genomic copy number variation in Chinese fine-wool sheep, identifying genes involved in sensory perception, nutrient metabolism, growth, and development, and highlighting significant selection on the RXFP2 gene.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

This study found that disrupting inflammasome signaling by eliminating caspase-1 and -11 in mice reduced skin inflammation and delayed the onset of disease, highlighting their role in skin disease pathogenesis.

This review discusses the relationship between SHBG, NAFLD, and PCOS and reports no new clinical results; the authors highlight low hepatic SHBG production as potentially significant in PCOS pathogenesis.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This study concluded that Wnt/β-catenin signaling, through Shh and Bmp pathways, is crucial for determining hair follicle fate in embryonic epidermal development.
