The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

This article reviews drug-induced pigmentation and reports no new clinical findings, highlighting difficulty in confirming drug associations due to factors like delayed onset and polypharmacy.

This review discusses epigenetic mechanisms in tissue repair across species and summarizes recent CRISPR-based technologies as promising tools for studying and enhancing tissue regeneration, but reports no new experimental results.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This research discusses the function and culture of human dermal papilla cells, noting their unique in vitro characteristics and the ongoing efforts to understand their role in inducing hair growth.

Fibroblasts from healthy donors can prevent changes seen in recessive epidermolysis bullosa simplex.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.

This review discusses the formation and maintenance of hair follicles through dynamic cellular changes and signaling pathways, presenting a comprehensive overview but providing no new experimental findings.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

This review explores how adaptive changes in cerebellar and vestibular subsystems may contribute to balance control, noting cellular mechanisms involved, but presents no new clinical findings.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

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 suggests that TIP39 and its receptor PTH2R, identified in human epidermis, may play a role in keratinocyte function and influence skin differentiation.

This study reports that oxytocin receptor expression in keratinocytes shows a potential relationship with touch sensory neurons, suggesting a role in skin sensitivity and the broader function of sensory neurons.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.

This review discusses the plasticity of stem cell populations and their ability to switch between functions for tissue homeostasis and regeneration, emphasizing environmental and hormonal influences, and reports no new results.

This review discusses the occurrence and impact of background histopathologic changes in nonhuman primate research, emphasizing the importance of understanding these factors to enhance study validity and interpretation.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

This review investigates the potential benefits of cinnamon supplementation alongside lifestyle changes for managing obesity and polycystic ovary syndrome, but it reports no new clinical results.

This study found that the systemic wrinkled skin phenotype in Xiang pigs involves gene expression changes and genetic variations associated with oxidative stress and extracellular matrix components, resembling features seen in Shar-Pei dogs.

This study reported that topical ω‐0‐acylceramide improved skin barrier function in Jack Russell Terriers with TGM1-deficient autosomal recessive congenital ichthyosis, normalizing skin pH and reducing transepidermal water loss.
