In this study, over-expression of FoxN1 in early life was associated with detrimental effects on thymic and skin epithelial development in mice.

In this study, researchers successfully generated functional and long-lived melanocytes from human embryonic stem cells, demonstrating their biocompatibility and high engraftability in mice, which may aid in developing treatments for pigmentary skin disorders.

In this study, various cellular responses and signaling pathways were examined in hair follicles after exposure to ionizing radiation, including the effects of Wnt3a treatment, with findings noted in apoptosis, DNA damage, and differentiation processes.

Results are not reported in this study, which investigated the effects of radiation on hair follicles and evaluated various cellular responses and signaling pathways, particularly focusing on WNT signaling and the impact of Wnt3a treatment.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.

Women with PCOS have overall higher body fat, not abnormal fat placement, and more insulin resistance.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

This study found that prenatal exposure to finasteride in rats led to permanent changes in developmental endpoints like anogenital distance and nipple retention, which were predictive of further reproductive tract malformations.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This study defines classification criteria for hair follicle dystrophy using a mouse model of chemotherapy-induced alopecia, providing tools for standardized hair damage assessment.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This review discusses the state-of-the-art knowledge on pseudoxanthoma elasticum, summarizing recent advancements in genetics, pathomechanisms, and potential treatments but reports no new clinical findings.

This abstract does not provide any new research findings or results.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This study found that disrupting Sox21 in developing teeth leads to severe enamel hypoplasia, regional osteoporosis, and abnormal hair formation, with impaired dental epithelial differentiation and regulation of hair follicle cell fate.

This study found that during amelogenesis in Msx2 null mice, a dysfunctional enamel organ developed due to abnormal epithelial transformation and lacked proper enamel formation.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This study reports that Wise is expressed in specific patterns during the morphogenesis of chick embryos, particularly in regions associated with known signaling molecules like Wnt, Bmp, and Shh.

This study found that nevoid basal cell carcinomas originate in the epidermis and the upper part of the hair follicle, showing similarities to nonnevoid basal cell carcinomas.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

This study suggests that Foxn1 expression in keratinocytes influences pigmentation in mice, highlighting differences in the molecular mechanisms between mouse and human pigmentation processes.

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

This review discusses the unique characteristics and possible pathophysiology of spiny keratoderma, reporting no new clinical results, but suggests that some therapies might alleviate symptoms.

This review discusses the complexities of diagnosing and managing PCOS in teens, focusing on its association with obesity and insulin resistance, but reports no new clinical findings.

This case study reports a rare instance of ectopic ACTH secretion from a primary lung neuroendocrine tumor in a young woman, highlighting successful diagnosis and treatment following symptoms of Cushing syndrome, with normalization of ACTH, glucose, and cortisol levels post-surgery.

This review explores the association between sleep disturbances, obstructive sleep apnoea, and metabolic consequences like Type 2 diabetes, but reports no new experimental results; the authors elaborate on existing knowledge and suggest complex interconnections with fat accumulation and various syndromes.

This study found that prenatal exposure to finasteride in rats disrupted male reproductive development, causing physical alterations such as delayed preputial separation and increased nipple retention.

This study found that Lrig1-positive cells in mouse epidermis are a previously unidentified source of adult interfollicular epidermal stem cells, which can contribute to sebaceous gland and epidermal lineage formation.
