This case report describes a 10-year-old twin boy with proximal hypospadias and undescended testis, highlighting the diagnostic and treatment evaluations for associated sex development disorders.

In this study, researchers identified compound heterozygous variants in the MBTPS1 gene associated with ectodermal dysplasia features in a 14-year-old female, broadening the known disorder spectrum linked to these genetic mutations.

This chapter reviews various fungal skin diseases affecting cattle but does not report new research findings; it focuses on rare, inherited, and congenital conditions like follicular dysplasia and cutaneous asthenia.

In this case report, a patient with Cronkhite-Canada Syndrome developed colon cancer and liver metastasis despite hormone therapy, highlighting the need for regular monitoring and early detection strategies.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

This study found that mimicking the XPD point mutation in mice resulted in trichothiodystrophy-like symptoms, supporting the role of basal transcription and DNA repair defects in the disease.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This review discusses the role of mechanical forces in skin homeostasis and disease development, including their impact on conditions like keloids, androgenetic alopecia, and acral melanoma, and reports no clinical results; the authors propose modifying these forces as a potential therapeutic strategy.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This study found that BNC2 is critical for hair follicle regeneration and other developmental processes, as Bnc2−/− mice exhibit incomplete hair follicle development and developmental defects, and BNC1 cannot substitute for BNC2.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

This case report indicates that retinoblastoma can occur in a microphthalmic eye and recommends using multiple imaging techniques due to potential differences in calcification visibility.

In this mouse study, the absence of the Ascl4 gene did not affect the development of hair follicles, teeth, or mammary glands, suggesting it is non-essential for these processes.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

This study used a mouse model to reveal that S100A4-positive cells, specifically fibroblasts and immune cells, play a crucial role in nipple development, essential for successful lactation, despite no issues with mammary morphology or milk production.

This research found that deleting the SLC3A2 gene in hair follicle stem cells disrupts their maintenance and proper differentiation, leading to hair follicle growth defects and altered skin regeneration through a YAP/Taz-dependent pathway.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.

This study presents a new method called scMC that effectively distinguishes biological from technical variation in single-cell genomics datasets, demonstrating its ability to accurately align and detect biological signals across various experiments.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This article presents an overview of uncombable hair syndrome, emphasizing its clinical and molecular characteristics and noting systemic manifestations such as neuropsychiatric, ophthalmic, and cardiopulmonary issues.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study reports that in MRL mice, loss of p53 does not impair ear regeneration, suggesting p21's potential role in this process may involve the Tgfb/Smad pathway.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This case report suggests that human dermal papillae conditioned media may accelerate wound healing in congenital aplasia cutis due to varicella infection.

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 found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.
