This study found that administering melatonin to ferrets can advance the timing of fur growth and reproductive cycles influenced by daylength and hormonal control.

This study describes the pelage cycle, hair types, and molt patterns in black-tailed deer, highlighting significant differences in hair properties among various developmental stages and populations.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

This study suggests that BLMP-1 is important for timely molting and oscillatory gene expression in C. elegans, indicating a potentially conserved mechanism for rhythmic skin regeneration.

In this retrospective study on pediatric craniospinal irradiation, researchers found that permanent radiation-induced alopecia occurred in 45.8% of patients, with higher radiation doses and treatment intensity being significant predictors, suggesting that defined dosimetric thresholds can support scalp-sparing planning.

This study found that adrenal hormones appear to inhibit winter fur growth onset in mink and may affect the duration of inactivity between fur growth periods.

Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.

In this study, researchers observed that fasting-induced molting in laying hens led to increased thyroid hormones, which may regulate feather molting by affecting hair follicle growth through specific signaling pathways, highlighting molecular changes during induced molting.

This study found that melatonin may enhance hair follicle stem cell viability by downregulating the nuclear receptor RORA, which otherwise inhibits cell proliferation and promotes apoptosis.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study found that melatonin combined with bromocryptine treatment in Spanish goats increased secondary hair follicle numbers and extended the cashmere growth phase during spring.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This study observed that alopecia in rhesus macaques follows a seasonal pattern, with the highest hair loss in spring, and varies with reproductive state, as pregnant females experience the most significant alopecia and lowest hair regrowth, which resumes postpartum.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

This study found that the season of the year does not significantly affect the hair regrowth rate or the telogen: anagen ratio in indoor-housed Labrador retrievers.

This study discusses the effects of collagen hydrolysates and the dipeptide Pro-Hyp on gene expression related to hair and epidermis development in mouse skin and reports no new clinical 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 found that serum prolactin and dehydroepiandrosterone levels did not determine the onset of mink hair growth cycles, though their metabolites may influence other aspects of hair growth.

This abstract omits specific findings and does not provide new research results.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

This study suggests that seasonal rhythm genes in cashmere goat skin are differentially expressed with changing daylight, potentially affecting hormone transformation and light sensitivity.

This study demonstrated that intraoperative bioprinting using a bioink with human adipose-derived extracellular matrix and stem cells achieved successful reconstruction of full-thickness craniomaxillofacial skin defects in rats, promoting wound closure, adipogenesis, and hair follicle-like structure formation within two weeks.

This study is the first to document alopecia in Guadalupe fur seals in the Northeast Pacific Ocean, finding that it may result from nutritional stress due to higher sea surface temperatures.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

This study reports that structural and biochemical analysis of steroid 5α-reductases clarifies how they mediate steroid reduction with NADPH, potentially aiding in designing targeted therapies.

This review discusses the role of Notch signaling in skin diseases such as Hidradenitis Suppurativa and Psoriasis, but reports no new clinical results.

This systematic review found no consistent evidence supporting the effectiveness of biotin supplementation for alopecia treatment unless there is a documented deficiency.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.
