This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

Pigs are a good model for studying human hair growth and disorders.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

In a rat model of chemotherapy-induced alopecia, this study found that low-level laser treatment significantly accelerated hair regrowth without affecting the efficacy of chemotherapy.

This study established a mouse model for Cushing's syndrome due to a specific Crh mutation, which may help explore the effects of glucocorticoid excess and evaluate treatments for corticosteroid-induced osteoporosis.

This study found that recombinant hepatitis B vaccine may increase the risk of alopecia areata onset in older predisposed mice but larger trials suggest this effect might lie within normal variation.

In this study, researchers found that the absence of P-selectin delays inflammatory cell recruitment and reepithelialization in fetal wounds, although scar formation still occurs in later gestation wounds.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

This review discusses the evaluation of animal models for hair research and regeneration, highlighting their importance and limitations, and calls for improved approaches to advance understanding of human hair diseases.

This study explores the neurobiology and genetics of barbering (hair and whisker biting) in laboratory rodents, and its potential links to stress, aggression, grooming, and stereotypic behaviors, highlighting its significance in experimental work with these animals.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This study found that ovine dermal papilla cells exhibit robust aggregation in culture, offering a model to investigate the regulation of hair follicle dermal papilla size.

This study reviews the development of a mouse model using pyroxylin to induce localized hair growth and shorten the hair cycle's resting phase, suggesting it as a platform for evaluating hair growth treatments, though further research is needed for human application.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

This study indicates that sheep prenatally androgenized with testosterone show wool fiber diameter changes that parallel the increased hair diameter in women with polycystic ovary syndrome.

This review discusses the use of experimental animal models to better understand the poorly understood mechanisms behind polycystic ovarian syndrome and reports no new clinical results.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study observed that young rat models, with naturally synchronized hair growth phases, developed total alopecia after chemotherapy and may serve as a better model for testing CIA protective treatments compared to adult rats.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This article reviews current research on animal models for hair regrowth treatments and reports no new findings; it highlights the need for studies comparing therapy efficiency and long-term safety.

This study demonstrated that allopregnanolone administration caused significant scratching in atopic dermatitis mice, and ethanol-induced scratching may be linked to increased brain allopregnanolone levels.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This review revisits the mechanisms of wound induced hair follicle neogenesis in mice and concludes that the process involves canonical WNT signaling activated by Fgf9 from γδ T cells, but more research is needed to fully understand its cellular bases.

This review discusses the role of δ-subunit-containing GABA A receptors and neurosteroids in temporal lobe epilepsy, highlighting their plasticity and potential pharmacological implications, without reporting new clinical results.

This study found that high-dose radiation can induce accelerated cellular senescence, inflammation, and loss of epithelial stem cells in mouse and human skin, contributing to radiation dermatitis.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

This study found that both PHDPE and ePTFE hair-bearing scaffolds were well tolerated in a rat model, with minimal infection or extrusion, though artificial hair showed progressive loss over time.

North American ginseng extract helped regrow hair in balding mice.

This study reported that in rat retinas under high pressure, allopregnanolone synthesis increased and helped reduce pressure-induced damage through GABAA receptors, suggesting potential therapeutic use in glaucoma.
