This article proposes a new classification system for cutaneous adnexal cysts based on their origin in the folliculo-sebaceous unit and sweat glands, aiming to clarify their categorization and origins.

This study found that donor age and culture medium significantly impact the quality of human full-thickness skin models, with implications for their use as animal model alternatives in research.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This article reviews the characteristics and therapeutic potential of neural crest cells from various sources, including embryonic and mature stem cells, but reports no new experimental results.

This research describes a two-step culture system for pluripotent mouse ES cells that produces hair follicle-like structures, providing a valuable model to study stem cell differentiation in vitro.

This study found that mitochondrial reactive oxygen species are crucial for normal epidermal differentiation and hair follicle growth, as demonstrated by impaired development in mice lacking these signals due to a keratinocyte-specific TFAM deficiency.

Pax9 is crucial for proper tongue surface development and preventing skin-like changes.

This study observed that basal cell carcinomas with matrical differentiation may derive from hair follicles, with .-catenin potentially playing a key role in tumor development and differentiation.

This study introduces genital sex differentiation parameters (GSDP) to analyze sexual differences in external genitalia and perineum development in mice, revealing varied sensitivity to androgen inhibition in genital structures.

This article discusses the classification and characteristics of infundibular squamous cell carcinoma and highlights the ongoing debate about its differentiation from other carcinoma types, reporting no new clinical results.

This study reveals that epidermal stem cell differentiation in mice involves dynamic transcriptional changes, with Keratin-10 transcription preceding gradual chromatin compaction shifts associated with differentiation.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

Whn is crucial for hair growth in certain areas by controlling a specific gene.

This study found that penile and clitoral differentiation in mice is influenced by androgen exposure, with penile features developing postnatally requiring prenatal and ongoing androgen presence.

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 found that active androgens activate lipogenic differentiation in human sebocytes expressing a functional androgen receptor, influencing gene expression and lipid synthesis, while also increasing apoptotic cell population over time.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found that different decontamination protocols caused varying levels of cuticle damage in hair, with aqueous buffer treatment resulting in the most substantial degradation.

In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

This study found that silk fibroin/sodium alginate scaffolds seeded with dermal papilla cells may accelerate skin repair and hair follicle regeneration in a rat model.

This study found that the progression of fetal skin development, marked by key features like the appearance of hair follicles and eccrine sweat glands, can help determine fetal age and predict congenital skin diseases.

This chapter provides an overview of skin physiology, aging effects, and how environmental factors like UV damage impact skin health, without presenting new research findings.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This study observed that vitamin D receptor knockout mice exhibit impaired epidermal differentiation and progressive hair loss, suggesting the importance of the vitamin D receptor in normal skin and hair follicle development.
