This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

In this case study, researchers reported that moth-eaten alopecia was the only clinical sign of secondary syphilis in a 28-year-old man from Nepal, and treatment with Benzathine Penicillin G led to complete hair regrowth within four months.

This case report suggests that madarosis, or eyelash loss, may be associated with mitochondriopathy, expanding the known causes of madarosis to include this condition.

This study found that knockout mice lacking intestinal hephaestin are smaller and anemic compared to wild-type, suggesting other mechanisms may compensate for iron absorption.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

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

This study found that epimorphin and a modified peptide, pep7, can stimulate hair follicles to shift from a resting phase to a growing phase in both an organ culture assay and in mice.

This study investigated the molecular mechanisms of hair follicle morphogenesis in Ordos fine-wool sheep, identifying differential genes related to primary and secondary hair follicles, and providing important insights for improving wool quality and breeding strategies.

This study found that mutations affecting hair keratin expression on Chromosome 15 in mice may cause altered hair and skin features similar to other known mouse mutations.

In this study, researchers identified that three homologous genes—ZmSPL10, ZmSPL14, and ZmSPL26—are crucial for the development of stigmatic papilla in maize, with triple knockout mutants lacking these genes showing almost no stigmatic papilla and significantly reduced kernel setting.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study describes a new mite species from marmots in a city park in Washington, noting that infested marmots displayed significant hair loss and tissue abnormalities.

This study found that in hairpoor mice, disruptions in hair follicle stem cell quiescence and signaling pathways lead to disturbed hair cycles, which may help explain alopecia development in Marie-Unna Hypotrichosis patients.

This case report details the dermoscopic features of bilateral cutaneous larva migrans in an adult male, noting similarities with lymphangioma circumscriptum but highlights that typical dermoscopy magnification may be insufficient for diagnosis.

This study developed a foxn1-deficient Xenopus laevis model using CRISPR/Cas9, observing reduced T-cell markers and altered immune responses in tadpoles, providing a nonmammalian model for immunological research.

This study found that extreme morning and evening chronotypes exhibited significant differences in the timing of circadian clock gene expression in hair follicle cells.

This collection of reviews, edited by Ken Lukowiak and Janis Weeks, explores diverse sensory systems across species, including olfaction, echolocation, magnetoreception, and visual adaptations, without presenting new experimental results.

This study describes unique anatomical characteristics of the skin and hair structures in the silver marmoset, including features such as thin epidermis, specialized nerve end-organs, and distinctive gland compositions.

This study observed that amelanotic melanocytes from human hair follicles appeared morphologically immature, suggesting they might not transfer melanosomes into keratinocytes.

This study found that loss-of-function mutations in the HOXC13 gene cause autosomal-recessive pure hair and nail ectodermal dysplasia, emphasizing its role in hair and nail development.

This study found a novel PAX9 gene mutation that may cause tooth agenesis and trichodysplasia in a studied family.

This study found that mirex and TPA promote papilloma formation in CD-1 mouse skin through distinct populations of mutant Ha-ras cells, resulting in additive tumor yields.

This study explored the genetic regulation of goose feather follicle development, identifying miR-200a as a key regulator that inhibits GEDF proliferation through the Wnt pathway, potentially impacting goose down quality and supporting selective breeding strategies.

This study observed that specific genes in cashmere goat skin exhibit a seasonal rhythm, potentially adapting to environmental light changes, which may affect downstream gene expression and physiological processes.

In this study, early prenatal treatment with Minoxidil, a lysyl hydroxylase inhibitor, partly improved cardiac outflow tract septation in Tbx1 mutant mice, suggesting that inhibiting collagen cross-linking may mitigate some effects of Tbx1 mutation associated with DiGeorge syndrome.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.
