In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

This study found that depleting fibroblasts in the skin does not affect the proliferative capacity of epidermal stem cells at various ages, suggesting robust compensatory mechanisms maintain skin functionality despite these cellular changes.

In this research, most cases of mammary and extramammary Paget disease were reported to express PRAME, expanding the understanding of its presence in cutaneous epithelial tumors, though its diagnostic utility is limited by overlap with other conditions.

This study details a step-by-step protocol for preparing mammalian skin samples, including hair follicles, for spatial transcriptomics to overcome challenges inherent in applying this technique to the skin.

This study explores the physical properties of hair from various wild mammalian species using polarized light microscopy, aiming to correlate these properties with the internal structures such as the medulla, cortex, and keratin cuticle.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This study found that mammary resident macrophages regulate mammary epithelium cell division and development, with implications for maintaining mammary stem cell activity and homeostasis.

This review discusses the role of mineral nutrients in human health, emphasizing the importance of dietary sources and education to prevent mineral deficiencies, and reports no new clinical results.

This article explores the evolution of mechanosensing and discusses the diverse forms and organization of touch receptors but reports no new research findings.

This review explores recent advances in understanding molecular mechanisms of tissue regeneration in mammals and suggests potential therapeutic targets, but it reports no new clinical results.

This review discusses the roles and mechanisms of chromatin remodelers and their subunits in mammalian development, but reports no new experimental results.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This review discusses the regenerative processes of deer antlers compared to other vertebrates and reports no new experimental findings, suggesting insights for regenerative medicine and cancer biology.

In this study, researchers found that hair follicle orientation in Fz6 −/− mice is disrupted and that hair may reorient itself over time through a self-organized process.

This review evaluates methods to study stem cell division patterns, particularly in the mammary gland, and discusses genetic factors affecting division modalities and their implications for breast cancer, but reports no new results.

This study found that mice lacking alkaline ceramidase 1 with elevated skin ceramide levels showed disrupted skin homeostasis, including altered hair follicle structures, increased water loss, and a hypermetabolism phenotype.

This study found that the formation of the fibre cuticle surface in Merino sheep is similar to the epidermal stratum corneum process and not from a modified plasma membrane as previously thought.

This review discusses key signaling pathways involved in tooth formation, highlighting their role in understanding tooth regeneration and potential therapies for dental abnormalities.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.

This review discusses the prevalence, diagnosis, treatment, and prevention of zoophilic dermatophyte infections in small exotic mammals and reports no new clinical findings; it emphasizes the need for veterinary guidance and public awareness.

This study observed that the active metabolite minoxidil sulfate promotes vascular relaxation by enhancing potassium permeability, which may inform understanding of minoxidil's antihypertensive and hair growth effects.

This study observed that buffalo teats have a melanin-rich epidermis, no hair follicles, and a complex structure with specific epithelial and muscular characteristics.

This report highlights two cases where trichoblastoma in the breast was initially misdiagnosed as malignancy due to diagnostic challenges in needle core biopsies, emphasizing the importance of expert dermatopathologic review.

This study observed that in adult mice, a cell-autonomous size control mechanism involving the RB pathway determines the timing of S phase entry in epidermal stem cells based on their size, while external microenvironment factors influence growth rates but not this intrinsic coupling.

This study found that biologic rhythms in mammoth hairs differed from those in modern human hair, with variations in growth rates and mineral content providing insights into the lifestyle and behavior of extinct species.

This article discusses melatonin's role in mammalian coat color and its potential in melanoma treatment when used with chemotherapy, but reports no new clinical results.
