This review discusses the role of growth factors and cytokines in hair follicle development and cycling, but reports no new clinical findings on treatments for hair growth disorders.

This study demonstrates that overexpression of K16 in transgenic mice disrupts normal keratinization, leading to hyperkeratosis, acanthosis, and alterations in the skin's epithelial cells.

In this study, cyproterone acetate at 2 mg daily was found to be as effective as higher doses in reducing hair growth for hirsute women over 12 months.

Mice with extra sheep genes had hair that fell out and regrew in cycles.

CYP11A1 is crucial for skin health and disease by producing important steroids.

This study concluded that cytokines and growth factors significantly regulate hair growth in vitro, with some completely inhibiting growth, such as EGF and TNFα.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

In this review, bioengineered materials incorporating growth factors and cytokines were reported to enhance wound healing by sustaining drug delivery, reducing dosage, and minimizing side effects compared to traditional treatments.

This study found that high doses of cyproterone acetate were associated with an increased risk of meningioma, especially with exposure longer than one year.

This study reported that antimicrobial and topical retinoid therapies led to significant changes in the lipid profiles of sebaceous follicular infundibulum, with increased triglycerides and ceramide subfractions observed.

This study found that trichoblastic fibroma and basal cell carcinoma cannot be differentiated by cytokeratin expression patterns, while trichoepithelioma lacks CK7 expression, distinguishing it from the other two neoplasms.

In randomized controlled trials, this research reports that cyclosporin is as effective as glucocorticoids for treating canine atopic dermatitis and has potential benefits for other immune-mediated skin conditions in dogs.

This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.

This study found that treatment with cyproterone acetate and ethinyl oestradiol increased hair density in women with diffuse androgen-dependent alopecia, particularly when serum ferritin levels were above 40 μg/l.

This study suggests that minoxidil activates PGHS-1, which may explain its hair growth-stimulating effects and could aid in designing more potent hair growth-promoting drugs.

This study concluded that a sequential regimen of prednisolone and cyclophosphamide, followed by low-dose prednisolone and azathioprine, achieved favorable results in most patients with diffuse proliferative and/or membranous lupus nephritis without significant toxicities.

This review found that adding cyproterone acetate to estradiol showed a subjective improvement in hirsutism versus placebo, but comparisons with other therapies revealed no clinical differences.

This study found that the oral contraceptive containing drospirenone (EE/DRSP) was as effective as EE/CPA in reducing acne lesions, sebum production, and hair growth in women with acne.

This study suggests that reversible hypopigmentation in homocystinuric patients may result from tyrosinase inhibition by homocyst(e)ine, with in-vitro experiments showing copper sulfate reversing this inhibition.

This study found that disrupting the Sox21 gene in mice led to progressive hair loss and regrowth, identifying Sox21 as a key regulator of hair shaft cuticle differentiation.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This study found that salinity stress in Arabidopsis thaliana root hairs may inhibit hair extension through changes in the tip-focused Ca(2+) gradient, while cytosolic pH remains unaffected.

This case report describes the topical application of cyclosporine in a man with alopecia universalis, which showed hair regrowth after 10 months of daily use, except where limited by a congenital nevus.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

In this study, three patients with extensive alopecia areata showed varying degrees of hair regrowth after 20 weeks of treatment with ustekinumab, a cytokine-targeting therapy.

This study found that both cyproterone acetate and spironolactone effectively reduced hair diameter and plasma testosterone levels in hirsute women, with no significant differences between the two treatments.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study found that a nonsense mutation in the Cst6 gene of mice leads to severe skin and hair abnormalities, suggesting that cystatin M/E is crucial for epidermal function and viability.

This review discusses the use of cyclosporine in dermatological conditions and its associated monitoring needs and potential side effects, but reports no new research results.

In this study, cyproterone acetate combined with estradiol dramatically improved hirsutism symptoms and significantly reduced plasma testosterone and androstenedione levels in patients over periods of up to three years.
