New hair regrowth model proposed, imiquimod found to kill skin cancer cells, T-cadherin loss linked to invasive skin cancer, no clear gene link to skin cancer after transplant, and study on children's hair loss shows male dominance and genetic ties.

This review discusses the effects of hydrogen peroxide in hair restoration surgery and other medical specialties, finding both potential benefits and risks, but reports no conclusive data for its optimal use in hair transplants.

In this study, researchers found that the synthetic stress hormone dexamethasone caused opposite effects on hair growth-related proteins, reducing SFRP2 and increasing SFRP3, which respectively stimulate and inhibit hair follicle cell proliferation in human dermal papilla cells.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

In this study, topical EGCG significantly reduced testosterone-induced hair loss and follicular apoptosis in mice, without altering testosterone or dihydrotestosterone concentrations.

This study reported that ELL is crucial for maintaining the proliferative capacity of the basal layer in human epidermal keratinocytes by stabilizing RNA polymerase II at the transcription start site.

This study found that methanolic extract of Ficus carica leaves induced apoptosis and inhibited proliferation in B16F10 melanoma cells, suggesting potential anti-cancer properties for further investigation in melanoma.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This review discusses the physiological roles of ovarian androgens in follicle development and atresia, emphasizing their contributions to polycystic ovary syndrome and normal follicle maturation but provides no new clinical results.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

In this study, miR-218-5p was found to enhance hair shaft growth and positively regulate the Wnt signaling pathway by targeting SFRP2 during skin and hair follicle development.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This study found that the absence of the stress-responsive protein Sesn2 increased hair cell susceptibility to gentamicin in the inner ear, indicating Sesn2's potential protective role against aminoglycoside-induced damage.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This study observed that nicotinamide can effectively inhibit human hair growth and promote hair follicle regression in cultured human scalp models without negatively affecting epidermal vitality, suggesting its potential as a hair growth inhibitor in cosmetic applications.

This review discusses the role of the Wnt/β-catenin pathway in skin wound repair and explores how photobiomodulation may affect chronic wound healing, but it reports no new clinical results.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This study found that all-trans-retinoic acid (ATRA) inhibits mink hair follicle growth by reducing dermal papilla cell proliferation and inducing apoptosis, likely through the TGF-β2/Smad2/3 pathway.

This article discusses how nutritional and environmental factors, along with antioxidant supplementation, may improve hair growth by mitigating the effects of androgens and reports no new clinical results.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study found that overexpression of miR-122 in balding hair follicles may induce apoptosis in human dermal papilla cells by repressing IGF1R, suggesting a new potential pathological mechanism in androgenetic alopecia.

This study investigated how the antioxidant MitoQ and the enzyme CYP19A1 influence mitochondrial function in androgenetic alopecia. In a mouse model, both CYP19A1 overexpression and MitoQ treatment improved mitochondrial health and reversed DHT-induced hair loss factors, suggesting potential therapeutic targets for this condition.

This study identified a network of interactions between miRNAs and mRNAs that involve key signaling pathways, suggesting new insights into the mechanisms behind androgenetic alopecia.

This study found that ApoEVs derived from mesenchymal stem cells improved cutaneous wound healing in diabetic mice by inhibiting macrophage pyroptosis and reducing oxidative stress levels.
