This study suggests that prenatal infusion of epidermal neural crest stem cells may improve certain neural markers and reduce cortical injury in a mouse model of methylazoxymethanol-induced malformations.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

This research observed that sheep and rabbit KAP6 genes, expressed in hair follicle cells, have high sequence similarity and indicate conservation due to evolutionary selection pressures.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

The researchers reported a rare case of invasive cutaneous squamous cell carcinoma of the scalp extending into bone and dura mater, successfully treated with surgery and skin flap repair, without metastasis observed at three months.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

This animal study found that Cinnamomi cortex water extract reduced prostate weight and improved histological changes in a benign prostatic hyperplasia model, suggesting potential as a treatment.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study developed the iCOUNT tool, which provides insights into stem cell behavior by tracking cell division events and molecular consequences in human and mouse neural stem/progenitor cells.

This study found that somatic mosaic mutations in the doublecortin gene may cause subcortical band heterotopia in male patients, and molecular analysis using hair roots is a useful detection method.

This study found that androgen impacted glucocorticoid signaling in the mouse brain only in the prefrontal cortex and substantia nigra, suggesting limited interaction between these hormones at high corticosterone levels.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

This review synthesizes the diverse roles of the transcription factor LHX2 in development, tissue maintenance, and injury repair across various organ systems, highlighting its potential therapeutic applications and significance in regenerative medicine, particularly in developmental disorders and tissue regeneration.

This study observed defects in hair cuticle cross-linking in some, but not all, mouse mutants with sparse or structurally unsound hair.

This study suggests that the adrenal gland may contribute to prostate cancer treatment resistance and indicates potential steroid production or dependency in ovarian cancer.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.

This research highlights the key interactions of hair cosmeceuticals, focusing on their effects on the hair fiber surface, cuticle, and cortex, which are crucial for protection and mechanical strength, particularly in damaged hair.

This study observed that long-term UV-A exposure and semi-permanent dye treatment can cause significant structural damage to human hair, particularly affecting the cuticle and cortex layers.

This study found that the hair of a 16th-century female mummy discovered in Paju was remarkably well-preserved due primarily to a calcium-based surface coating that likely inhibited moisture and microorganism infiltration.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

This review discusses the lipid composition of human hair across ethnic types, effects of damage on lipid content, and associated changes with diseases, but reports no new findings; further research is needed.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

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.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

Advancements in hair keratin research could lead to better hair health treatments.

In this animal study, Phellodendri Cortex extract reduced prostate tissue damage and inhibited 5α-reductase gene expression in rats with experimentally induced benign prostatic hyperplasia.
