This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study explored the significance of alopecia for women with breast cancer undergoing chemotherapy and found that their experiences varied, influenced by personal and social factors, and the support from adornments, groups, and family.

This research analyzed two ancient mammoth hair strands and reported distinct structural and elemental differences, including calcium, iron, and copper deposits, which vary with age and origin.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

This research presentation explored the roles of mammalian multi-copper ferroxidases in iron homeostasis and highlighted new insights into their functions, including non-iron-related ones, while discussing arsenic's role in microbial warfare as a potential antibiotic.

This case report documents the first known occurrence of an epidermoid cyst in the mammary gland of a 12-year-old female dog. The study emphasizes its benign nature but notes the potential for misdiagnosis and importance for pathologists to consider it during examinations.

This research identified genetic sequences that evolved at different rates in hairless versus hairy mammals, suggesting specific genetic changes contributed to the convergent evolution of hairlessness across various mammalian species.

This study suggests that specific genetic changes, including mutations in protein-coding genes and noncoding regions, have contributed to the evolution of hairlessness in multiple mammalian species.

This study identified intramembrane proteolysis as a key feature of Astrotactin2 maturation, providing insights into its role in planar cell polarity hair patterning.

This review discusses stem cells in the hair follicle, bone marrow, and intestinal epithelium and introduces a model where quiescent and cycling stem cells may coexists in "zoned" configurations.

This study suggests that Lrig1-positive cells form a previously unknown reservoir of interfollicular epidermal stem cells in adult mouse skin, influencing epidermal proliferation and hair follicle development.

This study demonstrates that Sox2-positive dermal papilla cells specify particular hair follicle types by showing heterogeneity in gene expression and pathway activation in these cells.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This study found that T cytokeratins appear more gradually and with complex coexpression patterns in developing nail structures compared to the more abrupt transition in hair follicles.

This study found that while the KRTAP gene family is unique to mammals, humans have a similar number of these hair gene types as other primates despite having less body hair.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

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.

Keratins change and are modified differently in skin layers and body parts.

This review discusses the use of animal models to study alopecia areata and reports no new experimental results, emphasizing the potential for these models to explore the disease's genetics and treatment.

This study found that keratin genes in the epidermis of aquatic mammals like cetaceans have evolved to replace stress-inducible keratins K1 and K10 with constitutively expressed K6 and K17, suggesting adaptations to their environment.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This study found that 4-MA is a potent inhibitor of testosterone 5α-reductase in human tissues, promising potential for treating androgen-dependent skin conditions like male pattern baldness.

This study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

This study found widespread losses of g-type lysozyme genes across various mammalian lineages, with both gene copies extensively lost in cetaceans and sirenians, and linked this to hairlessness in these fully aquatic mammals.

This study reveals that transglutaminase activity is widespread in integumentary structures of mammals and birds, suggesting it plays a significant role in the cornification of hard skin appendages like nails and feathers.
