This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This study observed a high degree of plasticity in somatosensory axons innervating Merkel cells in mouse skin, finding that both axons and Merkel cells underwent dynamic remodeling, with their interactions influencing axonal branching and maturation.

This study observed that Merkel cells and their associated somatosensory axons in mouse skin exhibit significant plasticity, remodeling dynamically to maintain homeostasis. Axonal branching patterns were notably influenced by Merkel cells, suggesting epithelial-neural interactions play a key role in axonal plasticity and patterning.

This review explores the use of skin penetration enhancers like Transcutol® in various formulation systems, discussing their mechanisms and effectiveness in improving transdermal drug delivery without breaching the skin.

This report discusses a case of a rare congenital neck mass called a "wattle" or congenital cervical tragus, emphasizing its histological features and its association with other branchial arch anomalies.

This study interpreted McDonald's Father's Day advertising posters using semiotic analysis, finding that the imagery and text symbolically represent a father figure and McDonald's branding to celebrate the occasion.

This review discusses three decades of progress in feather development, regeneration, and evolution, with no new experimental results; it highlights feathers' potential as a model for morphogenesis studies.

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 introduces a magnet-assisted fabrication strategy for creating complex 3D soft bioscaffolds, demonstrating its effectiveness by producing structures with overhangs and supporting biohybrid actuators, promising advancements in biomedical applications.

This study found that certain chemotherapeutic agents, such as cyclophosphamide, disrupt feather formation and induce hair loss in mice by inhibiting cell proliferation through sonic hedgehog gene downregulation.

This study found that excess vitamin A induced stable glandular morphogenesis and mucous metaplasia in embryonic mouse vibrissa follicles, even after switching to standard medium.

Dermoscopy is useful for diagnosing and monitoring discoid lupus erythematosus by showing specific skin patterns.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This study in mice found that MEIS2 expression in mesenchymal dermal cells is crucial for the formation of whiskers and the initial steps of epithelial placode development, independently of sensory nerve innervation or Foxd1 expression.

In this study, extracellular vesicles derived from amniotic fluid stem cells enhanced fetal lung development in models of pulmonary hypoplasia, showing promise for therapeutic application.

This study found that overexpression of NSD3 in the mammary gland of transgenic mice led to mammary hyperplasia, dysplasia, and invasive ductal carcinoma, mirroring patterns seen in human breast cancer.

This research describes a crucial role for Meis2 expression in mesenchymal cells derived from the neural crest for whisker formation, showing that whiskers can develop without sensory innervation or FOXD1 expression, highlighting an early function of MEIS2.

This study used atomic force microscopy to image surface structures of human epidermal melanocytes, hair follicle amelanotic melanocytes, and mouse melanoma cells, revealing differences in branch structure and granule distribution.

This case report describes a rare instance of sebaceous trichofolliculoma identified in an 18-year-old boy, characterized by a dermal nodule on the nasal bridge with distinct histological features.

This review discusses a "stochastic multi-hit model" to explain the onset, progression, and recurrence of vitiligo and other autoimmune skin diseases, emphasizing genetic and environmental influences, immune cell interactions, and unexplored mechanistic gaps.

This study observed a high prevalence of PCOS among young female-pattern hair loss patients and suggested that AMH levels might be more indicative of FPHL than traditional androgens.

This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.

This study reported that canine dermal papilla cells showed a distinct growth pattern and strong collagen IV and laminin staining compared to dermal fibroblasts.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

This study generated a pharmacophoric model for both isoforms of steroidal 5α-reductase using 6-azasteroids, providing a structural framework for designing new inhibitors.

This study found that methylene blue staining may reveal anatomical details of intraepidermal nerve fibre endings in the rat mystacial pad with greater clarity than the zinc iodide-osmium tetroxide technique.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study found that among 17 beta-(N-ureylene-N,N'-disubstituted)-4-azasteroids, those with an N'-phenyl moiety were the most effective inhibitors of human type I 5 alpha-reductase.

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.

In this study, researchers propose that the EDAR V370A allele's positive selection in East Asian populations may be linked to stable aquatic resources from Late Pleistocene ecosystems in northern China, suggesting a "nutritional niche construction" framework where these resources offset the allele's metabolic costs.
