In this study, topical trypsin treatment following depilation in a mouse model induced cell death at the follicular papilla, delaying hair growth and pigmentation.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This case report describes an 8-year-old boy with impetigenic scabies on his scalp, which responded well to treatment with topical permethrin, oral antihistamines, and antibiotics.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

Teledermatology reduces unnecessary in-person visits and improves care.

This chapter offers detailed histopathologic insights into various pilosebaceous unit diseases, discussing diagnosis without reporting new results.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

In this study, researchers cloned a two-year-old Pomeranian with Alopecia X after its accidental death and found that the cloned dog developed the same hair lesions at the same age, suggesting the condition is genetically driven rather than environmentally influenced.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

Hair proteins change location and structure as hair cells mature.

In this study, researchers found that the cashmere hair growth cycle is divided into three periods and key genes like KAP and KRTAP are positively correlated with these cycles in cashmere goats.

This review discusses the evolution of lineage-tracing strategies over the past century, emphasizing their role in identifying progenitor cells and resolving debates about cellular origins, with no new results reported.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

This study found that Fos protein expression is closely linked to epithelial cell differentiation, particularly during cornification and cell death, with overexpression observed in keratinization-blocked mutant epidermis.

This study reports that K7 expression patterns observed in mice are similar to those in humans, revealing previously unreported expression in the gastrointestinal tract, tongue, and various "hard" epithelial tissues.

This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This review summarizes recent insights into the developmental origin and formation of tissue stem cells across various organs, reporting no new experimental results.

Direct-to-consumer teledermatology is not effectively reaching underserved populations due to language, technology, and insurance barriers.

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 review discusses Becker's Melanosis and Hypertrichosis in young males, summarizing cases observed in Melbourne with clinical and histological analyses, but reports no new clinical findings.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

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 study provides direct evidence that the Wnt-β-catenin pathway promotes TERT expression in stem and cancer cells, linking tumorigenesis with pluripotency.

This study identified and updated the annotation of 61 keratin genes in dogs and horses, improving the genome annotation in these species through RNA-seq data comparison.

This review discusses the complex diagnosis and management of telogen effluvium, noting its high prevalence, psychosocial impact, and need for quantitative diagnostic techniques, but it reports no new research findings.

The K15 promoter effectively targets stem cells in the hair follicle bulge.

This study identified a population of GFP-expressing nestin-positive cells in transgenic mice hair follicles that varied in location during different hair cycle phases, suggesting a shared relationship with neural stem cells.
