The article concludes that studying how skin forms is key to understanding skin diseases and improving regenerative medicine.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study found that fluorescence excitation spectroscopy could be a promising noninvasive tool for assessing the effects of comedolytic agents like retinoids on acne-like lesions in rhino mice.

In this study, hydroxychloroquine use was associated with a delayed onset of integument damage in SLE patients, while higher disease activity over time predicted quicker damage development.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

This source reports that two noninvasive tests, the pull test and a modified wash test, can help diagnose and determine the severity of different types of hair loss in women by assessing hair shedding and characteristics, offering a simple and cost-effective evaluation method.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.

This case report described a young Himalayan kitten in Indonesia with notoedric mange, treated successfully with topical selamectin and sarolaner, highlighting the importance of early diagnosis and management to prevent reinfestation, especially in urban areas.

This study identified a new S100 fused-type protein, scaffoldin, in reptiles and birds and suggests that SFTP-positive epithelia serve as scaffolds for the growth of various skin appendages, indicating a common evolutionary origin.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

This article proposes a hypothesis that KRT75, a protein found in hair follicles, was evolutionarily co-opted by ameloblasts during the development of prismatic enamel in synapsids, but reports no new results.

In this study, the researchers found that mammalian hair likely evolved through the adaptation of existing structural proteins, as similar cysteine-rich α-keratins were identified in chicken and lizard genomes, suggesting pre-mammalian origins.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study examined the complex morphology of the cornified claw sheath in domesticated cats, uncovering structures and growth patterns that help maintain sharp claw tips essential for climbing and prey capture.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.

This study highlights the loss of hair-type keratin genes in cetaceans compared to terrestrial mammals, suggesting a potential adaptive role linked to their hairless phenotype and habitat changes.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

This paper reviews seven major systemic causes of hair loss and provides a clinical evaluation framework but reports no new experimental results.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This study describes a follicular automaton model that simulates human hair cycles and may replicate hair pattern evolution seen in diffuse or androgenetic alopecia.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study investigated pangolin skin genetics, finding that while sweat gland-related genes are not inactivated, several genes related to sebaceous gland function are, which highlights complex evolutionary adaptations in mammalian skin.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

This article reviews various topics discussed at a workshop on hair disorders, focusing on hair biology, diagnosis, and challenges in therapy evaluation, without presenting new clinical findings.

This review outlines the evolution of hair follicle engineering and its foundational discoveries, but reports no new experimental results.

In this study, researchers formulated a hair tonic using various herbal extracts and reported effective antifungal and antibacterial properties, along with good consistency, spreadability, homogeneity, appearance, and pH balance.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.
