This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study found that keratin genes in the epidermis of aquatic mammals like cetaceans have evolved to replace stress-inducible keratins K1 and K10 with constitutively expressed K6 and K17, suggesting adaptations to their environment.

This study identified a new S100 fused-type protein, scaffoldin, in reptiles and birds and suggests that SFTP-positive epithelia serve as scaffolds for the growth of various skin appendages, indicating a common evolutionary origin.

This study found that 9 out of 12 women with acne or alopecia showed subjective improvement with finasteride treatment despite having normal free testosterone levels, suggesting a potential role of 5alpha-reductase activity.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study found that autophagy plays a role in sebaceous gland function and sebum composition control in mice lacking the Atg7 gene in keratinocytes.

This study reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

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.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

In this study on mouse preputial glands, suppressing ATG7-dependent autophagy delayed age-related changes, affected lipid metabolism, and reduced pheromone production, highlighting autophagy's roles in glandular homeostasis and cell breakdown.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study suggests that keratinocytes in skin and mucous membranes might be involved in prion disease transmission due to their expression of PrPc, potentially serving as an entry point for prions.

This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

This study found that inhibiting autophagy in mouse preputial glands alters lipid metabolism, delays aging-related duct changes, and reduces pheromone production, indicating autophagy's critical role in gland homeostasis and cell breakdown during secretion.

This study found that autophagy in the preputial glands of mice plays a crucial role in regulating lipid and fatty acid metabolism, as well as pheromone production.

This study found that DPP4 is significantly involved in matrix deposition and fibrosis in human skin fibroblasts, although the exact functions of DPP4 remain unclear.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

This study found that Anovlar effectively reduced pain in severe dysmenorrhea cases and regulated cycles in oligomenorrhea patients, but some side effects and occasional treatment failures were reported.

This report of two pediatric cases suggests that careful diagnosis of scalp lesions as possible dermatophytic infections is crucial to avoid inappropriate surgical treatment and facilitate proper conservative management.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This case report documents the first known instance of an ectopic sebaceous gland and duct within a hair follicle in a 21-year-old male with persistent acneiform eruption.

In this case study, an 11-year-old girl with a Cladosporium scalp infection showed significant improvement in hair growth and appearance after treatment with itraconazole.

This case study describes a 4-year-old boy whose neck tumor was initially misdiagnosed as scrofuloderma before being correctly identified as a pilomatricoma, underscoring the need to include pilomatricoma in differential diagnoses for persistent skin lesions.

This article reviews the occurrence of ectopic sebaceous glands in hair follicle matrix during hair embryogenesis and reports no new clinical results, indicating unknown pathogenesis and clinical implications.

This study discusses incidental findings of syringomas and syringomatous proliferations in areas of scalp alopecia, suggesting they may be secondary to reactive changes from subclinical alopecia.

This report describes a unique case of linear lichen planus pigmentosus on the face with histological features of lichen planopilaris, which has not been documented before.
