research The Role of Immature and Mature Adipocytes in Hair Cycling
Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.
research Differential Suppression of Testosterone and Estradiol in Hirsute Women With the Superactive Gonadotropin-Releasing Hormone Agonist Leuprolide*
Leuprolide effectively reduces hair growth in hirsute women at higher doses.
research Bilateral Leydig Cell Hyperplasia: A Rare Cause of Postmenopausal Hirsutism
An unusual growth of Leydig cells in a woman's ovaries caused her excessive hair growth, which was treated successfully with surgery.
research Postmenopausal Occult Ovarian Disease With Hirsutism – A 6-Year Follow-up Course
Leydig cell tumors can cause hormone issues in postmenopausal women even if imaging looks normal.
research MON-LB044 Bilateral Ovarian Hyperthecosis: A Benign and Unusual Cause of Postmenopausal Hirsutism
Bilateral ovarian hyperthecosis is a rare but treatable cause of increased facial hair in postmenopausal women.
research 1332 Understanding the role of glycogen metabolism in human hair follicle biology
Glycogen metabolism is important for energy and processes in human hair follicles, and hair follicles may produce glucose from lactate.
research Vitamin B6 promotes the activation of primordial follicles through the PI3K/Akt signaling pathway
Vitamin B6 may help activate dormant follicles.
research The Stem Cell Quiescence and Niche Signaling is Disturbed in the Hair Follicle of the Hairpoor Mouse, an MUHH Model Mouse.
Hair follicle stem cells in hairpoor mice are disrupted, causing hair loss.
research Evaluation of Gene Expression Patterns in Micrografts Demonstrate Induction of Catagen-Like Processes During Storage
Storing hair follicle micrografts for longer times can cause them to enter a state similar to the natural hair shedding phase, which might impact hair transplant results.
research 1325 Extensive hair growth stimulation and follicle normalization with transplanted hair follicle associated pluripotent (HAP) stem cells in athymic nude mice
Transplanted stem cells from hair follicles significantly boosted hair growth and normalized follicles in certain mice.
research Cell proliferation during fibre growth initiation in ferret hair follicles
Ferret hair growth starts between 0 and 4 days after melatonin treatment, with cell growth peaking in the hair germ and declining as the hair matures.
research Resting no more: re‐defining telogen, the maintenance stage of the hair growth cycle
The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
research Hair Follicle Pluripotent Stem (hfPS) Cells
research Morphological analysis of in vitro human hair growth
Human hair follicles can grow and stay healthy for up to 8 days in a lab setting.
research Structural variations and distributions of human Body follicles
Human body follicles have diverse structures and functions important for health.
research 036 Expanded T cells under lymphopenic condition exhibit memory phenotype and infiltrate around hair follicle
T cells with memory features grow in number and gather around hair follicles when there are not enough immune cells.
research Epithelial Cells in the Hair Follicle Bulge do not Contribute to Epidermal Regeneration after Glucocorticoid-Induced Cutaneous Atrophy
Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.
research Effect of Leuprolide and Dexamethasone on Hair Growth and Hormone Levels in Hirsute Women: The Relative Importance of the Ovary and the Adrenal in the Pathogenesis of Hirsutism*
The ovary mainly causes high testosterone in PCO, while the adrenal gland is the main source in IH.
research Determination of Secondary Follicle Characteristics, Density, Activity, and Hoxc13 Expression Pattern of Hexi Cashmere Goats Breed
Hexi cashmere goats' hair growth varies by stage, with Hoxc13 linked to hair activity.
research Supplementary Material for: Life of the B10 mouse: a view from the hair follicles and tissue stem cells
Mouse skin and hair aging starts at 200 days, with changes in hair follicles and more white hairs as signs of aging.
research Morphogenetic Events in Hair Follicle Heterotypic Spheroids
Researchers developed a method to create artificial hair follicles that may help with hair loss treatment and research.
research El folículo piloso: una importante fuente celular en ingeniería tisular
Hair follicles are a key source of stem cells for skin repair and could help treat baldness.
research Expression of morphogens during human follicle development in vivo and a model for studying follicle morphogenesis in vitro
Hair follicle development involves complex interactions between skin layers and cells, but many details are still unknown.
research Cryopreservation of engineered hair follicle germs for hair regenerative medicine
DMSO and microfinger devices show promise for preserving hair grafts for hair loss treatments.
research Androgenic alopecia and hirsutism in a 73-year-old woman: careful re-evaluation of 'normal' imaging findings may lead to a rare diagnosis
A 73-year-old woman's unusual hair loss and growth led to the discovery of a rare condition causing too much testosterone, which improved after her ovaries were removed.
research Folliculin: A surprising molecular brake in the human hair follicle
Folliculin slows hair growth, and blocking it might help treat hair loss.
research 1349 Inducing fate changes at the hair follicle stem cell nice
The study found that aging hair follicle stem cells change behavior, leading to hair loss, but drugs targeting these cells may help restore hair growth.
research Additional file 12 of Time-course RNA-seq analysis reveals stage-specific and melatonin-triggered gene expression patterns during the hair follicle growth cycle in Capra hircus
Melatonin affects when and how goat hair follicle genes turn on and off during growth cycles.
research Studies on the biochemistry and morphology of freshly isolated and maintained rat hair follicles
