This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

In this study, the combination of arsenic toxicity and hypoxia in Arabidopsis thaliana altered root development through stress-specific root growth phenotypes and changes in phosphate starvation response, energy metabolism, and redox signaling.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

This study found that applying AGN root extract containing decursin to mouse skin accelerated hair growth and altered inflammatory cytokine levels compared to a control.

This study found that during dialysis, lower plasma-potassium levels were associated with hyperglycemia, suggesting potassium correction is vital when using glucose-rich dialysate.

This study observed that decreased nucleolar organizing region protein synthesis in hair root cells is correlated with hair loss in humans.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that asebic mice exhibit abnormal sebaceous gland differentiation and insufficient sebum production due to defective regulation of cell processes, despite possessing normally developing sebaceous glands initially.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

In human follicular cells, this study found that an Annurca apple-based dietary supplement may stimulate the production of hair keratins, suggesting potential benefits for hair growth.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.

This study found that long-term exposure to high pH extends root hair elongation by altering actin filament arrangements and vesicle trafficking, but disrupting ADF8/11 function shortens root hairs by affecting these processes.

This study found that root hairs in maize, wheat, and finger millet continued to grow beyond the typical root hair zone when grown with the Turface® fertigation system, highlighting potential for understanding root hair dynamics and crop improvement.

In this study, rabies virus antigens were detected in the outer root sheath of the follicle-sinus complex in the muzzle skin of rabid dogs, suggesting its usefulness as an alternative diagnostic specimen.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study found that GPC1 is a crucial regulator of angiogenesis in human dermal microvascular endothelial cells, indicating its potential as a target for treating alopecia.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

In this study, the PLP2 gene was found to promote secondary hair follicle development in Liaoning cashmere goats, with its expression negatively regulated by melatonin and potentially affecting follicle development via the BMP pathway.

This case report describes a 45-year-old woman with diffuse nonscarring alopecia characterized by hair thinning, increased catagen/telogen follicles, and mild inflammatory infiltrate, highlighting the diagnostic findings via scalp dermoscopy and biopsy.

This study used TMT-based quantitative proteomics to analyze the development of secondary hair follicles in fetal sheep, revealing increased follicle density and key proteins involved, such as COL1A1 and THBS4, indicating their potential role in wool quality traits.
