In this study, researchers examined the skin of neonatal rabbits and found that most hair follicles were in the terminal stage, with hair shafts protruding through the epidermis, but noted the absence of sweat glands.

This case report describes three Iranian men with gradual reddish-brown pigmentation on their cheeks and preauricular areas since childhood, unresponsive to sunblocks and topical steroids.

This case study documents the co-existence of trichorhinophalangeal syndrome and loose anagen syndrome in a patient, highlighting a previously unreported association between the two conditions.

ZPK helps skin cells mature and may affect skin health.

Skin and hair cells release serotonin and histamine naturally, which could help improve skin health.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study observed that the expression of certain keratins during human epidermal development marks the tissue's commitment to stratification and keratinization processes.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study found that overexpression of the calcium sensing receptor in transgenic mice accelerates epidermal differentiation and hair growth, suggesting its role in enhancing calcium signaling and interaction with other pathways.

This study suggests that nephronectin (NPNT) could serve as a novel prognostic marker for poor prognosis in a subgroup of breast cancer patients, associated with specific NPNT staining patterns.

Nephronectin is linked to worse outcomes in breast cancer and helps cancer spread.

This study in rats with a portocaval shunt observed severe ultrastructural damage to the inner ear, associated with zinc deficiency and symptoms resembling liver cirrhosis in humans.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This study identified a new 65 kD and 48 kD keratin pair expressed in specific mouse epithelial sites, suggesting a unique evolutionary branch of hair-related keratins.

This article discusses the importance of understanding the skin's structure and function for comprehending both healthy skin biology and skin disease pathophysiology, but reports no new findings.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This study reports that caspase-14's expression pattern in the epidermis and hair follicles is highly conserved across diverse mammalian species, suggesting its early evolutionary role in mammalian skin maturation.

Protease Nexin-1 is found in human hair growth cells and is affected by male hormones.

In this case study, an 8-year-old female Huacaya alpaca displaying male behavior was diagnosed with an ovarian benign interstitial (Leydig) cell tumor, indicated by elevated testosterone levels.

The researchers reported that the antipsoriatic compounds 1,25-dihydroxy-vitamin D3 and calcipotriol thinned the living cell compartment in organotypic ORS cultures by accelerating the differentiation pathway rather than affecting proliferation.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.
