research Seasonal Moulting in Adult Male Raccoon Dog (Nyctereutes procyonoides)
Adult male raccoon dogs shed their winter fur in spring and grow new fur for winter in autumn.
research Studies of normal moult and of artifically induced regeneration of pelage in peromyscus
Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.
research Bilateral adrenalectomy induces early onset of summer fur growth in mink (Mustela vison)
Removing mink's adrenal glands causes their summer fur to grow earlier.
research The role of the adrenal glands in regulating onset of winter fur growth in mink (Mustela vison)
Adrenal glands delay the start of winter fur growth in mink.
research Adrenocorticotropic Hormone (ACTH) But Not Alpha-Melanocyte Stimulating Hormone (a-MSH) as a Mediator of Adrenalectomy Induced Hair Growth in Mink
ACTH promotes hair growth in mink, but α-MSH does not.
research Recent Progress in Prostaglandin F2αEthanolamide (Prostamide F2α) Research and Therapeutics
New research on prostamide F2α has led to treatments for glaucoma and eyelash growth and may have more medical uses.
research Analyses of regenerative wave patterns in adult hair follicle populations reveal macro-environmental regulation of stem cell activity
Hair follicle stem cells are controlled by their surrounding environment.
research The effect of melatonin implants administered from December until April, on plasma prolactin, triiodothyronine and thyroxine concentrations and on the timing of the spring moult in cashmere goats
Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.
research Human Dermal Fibroblasts Demonstrate Positive Immunostaining for Neuron- and Glia- Specific Proteins
Fibroblasts can be mistaken for neural cells, so functional validation is needed.
research Scaling dermatosis in three dogs associated with abnormal sebaceous gland differentiation
Three dogs with a rare skin condition improved with treatment.
research Effects of maintaining solstice light and temperature on reproductive activity, coat growth, plasma prolactin and melatonin in goats
Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.
research Effect of constant-release melatonin implants and prolonged exposure to a long day photoperiod on prolactin secretion and hair growth in mouflon (Ovis gmelini musimon)
Melatonin implants and long daylight hours alter the timing of hormone release and hair growth in mouflon sheep.
research The transcriptional landscape of seasonal coat colour moult in the snowshoe hare
Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.
research Environmental Influences on the Hair Follicle
Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.
research The effects of extended photoperiod and warmth on hair growth in ponies and horses at different times of year
Timing of light therapy affects horse coat growth, with photoperiod being crucial.
research The control of hair growth: An overview
Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.
research An analysis of canine hair re‐growth after clipping for a surgical procedure
Dog hair grows back in about 14 weeks after being clipped for surgery, and the season doesn't really affect this growth rate.
research Hair coat characteristics in Friesian heifers in the Netherlands and Kenya : experimental data and a review of literature
Friesian heifers take about 18 months to adapt to Kenya's climate, with hair changes not strongly linked to weight gain.
research Neural crest cells and their potential therapeutic applications
Neural crest cells could be used in regenerative medicine due to their ability to become different cell types.
research Prolactin and the Skin: A Dermatological Perspective on an Ancient Pleiotropic Peptide Hormone
Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.
research Differences in Expression of Specific Biomarkers Distinguish Human Beard from Scalp Dermal Papilla Cells
Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.
research Function and underlying mechanisms of seasonal colour moulting in mammals and birds: what keeps them changing in a warming world?
Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.
research Melatonin and the hair follicle
Melatonin helps regulate hair growth and protects the hair follicle from stress.
research Androgens and human hair growth
Androgens can cause hair growth in some areas and hair loss on the scalp.
research An integrative view of mammalian seasonal neuroendocrinology
The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
research The C3H/HeJ mouse and DEBR rat models for alopecia areata: review of preclinical drug screening approaches and results
Both mouse and rat models are effective for testing alopecia areata treatments.
research Adrenal steroid hormone concentrations in dogs with hair cycle arrest (Alopecia X) before and during treatment with melatonin and mitotane
Melatonin and mitotane treatment led to hair re-growth in 62% of dogs with Alopecia X, but this was not always linked to normal hormone levels.
research Androgen receptors are only present in mesenchyme-derived dermal papilla cells of red deer (Cervus elaphus) neck follicles when raised androgens induce a mane in the breeding season
Red deer only have androgen receptors in neck hair cells for mane growth during breeding season.
research Characterization and causal investigations of an alopecia syndrome in Australian fur seals (Arctocephalus pusillus doriferus)
Young female Australian fur seals are losing hair due to low tyrosine and zinc levels and high pollution exposure.
