This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

In a clinical phase I/IIa study, subcutaneous injections of the peptide FOL-005 increased hair growth by 8% and were safe for treating alopecia.

This study demonstrated that biochemical analysis of proteins from fetal skin biopsies is feasible, potentially enhancing prenatal diagnostic capabilities for protein-related disorders.

This narrative review suggests that intermediate filaments like vimentin and keratin play a significant role in various stages of viral infection, presenting potential antiviral intervention targets.

This review discusses the recent advancements in understanding how keratins influence cytoarchitecture, cell dynamics, and disease processes but reports no new clinical results; the authors highlight its roles in development and diseases like cancer.

In this study, researchers analyzed trichoscopy findings in black patients with FFA to aid in precise diagnosis and treatment, highlighting the importance of understanding disease characteristics to improve hair care in this group.

This article describes a new method for staining hair fibers that visualizes keratin filaments without the need for OsO4 fixation or sulfur bond breakage, but it provides no new experimental results beyond the method itself.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study identified Activin A and follistatin as key regulators of hair cell differentiation in the mammalian auditory sensory epithelium, with Activin A signaling influencing the timing and pattern of cell differentiation.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

This study suggests that infrared thermography may be a useful noninvasive tool for diagnosing active phases of frontal fibrosing alopecia when combined with dermoscopy.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

In this study, gene inactivation in mouse hair follicle stem cells lacking ILK impaired wound healing by reducing their progeny’s contribution to the regenerating epidermis, but did not affect hair follicle regeneration.

This dissertation reveals that FERONIA, a cell wall-binding receptor kinase, plays a crucial role in regulating plant functions such as sugar signaling, pollen tube reception, and RAC/ROP-mediated auxin signaling.

In this study, researchers conducted an exploratory re-analysis of miRNA dysregulation and aging-related target enrichment using publicly available data on female pattern hair loss, comparing 3 FPHL scalp samples to 5 healthy female controls, and emphasized that the findings are preliminary and require further validation.

The LTF gene may help predict and manage nonspecific orbital inflammation.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

Activin A speeds up ear hair cell differentiation, while Follistatin slows it down.

This study tested the acute toxicity of Ficus platyphylla methanol leaf extract in Wistar rats and found no mortality or significant liver enzyme changes at doses up to 5000 mg/kg, suggesting a high margin of acute safety and supporting its traditional use under short-term exposure.

In this study, researchers discovered that fat grafting helps reduce dermal fibrosis in radiation-injured mouse skin by decreasing specific fibroblast subpopulations associated with Fra/c-Jun signaling.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

The Fas/FasL pathway may play a role in alopecia areata.

In this case report, a 15-year-old golden retriever with calcinosis cutis showed accelerated improvement in FLE-treated skin infections compared to untreated areas, highlighting FLE's potential as a treatment adjunct.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This study found that Caucasian female hair is denser than Asian female hair in the occipital region regardless of treatment but thinner in diameter in both the frontal and occipital regions.

In this study, feeding Gymnocypris eckloni with Flammulina velutipes residues enhanced foregut morphology and beneficially altered gut microbiota, highlighting potential improvements in intestinal health for aquaculture use.

This article reviews frontal fibrosing alopecia, exploring its characteristics, demographics, and associated conditions, and calls for controlled trials due to an increase in worldwide cases; it reports no new findings.

This study found that apoptosis was more prevalent in hair follicles of women with female pattern hair loss, particularly in miniaturized follicles, and was associated with follicular inflammation.
