This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This study found that low oxygen conditions and ECM degradation products increased the proliferation and migration of perivascular stem cells without altering their phenotype, suggesting potential roles in tissue repair.

This study found that type II keratins in proliferating epithelial tissues are phosphorylated at a conserved motif during mitosis and stress, impacting keratin solubilization and reorganization.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

In this study, researchers developed a wearable red and blue LED patch and a sprayable fibrin gel to treat infected wounds at home, demonstrating effective infection control and enhanced wound healing in diabetic mice and minipigs.

In this case series, four adults developed severe, disabling multisymptom illness potentially linked to fluoroquinolone use, which persisted and progressed even after discontinuation of the drug.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

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.

In this study, researchers found that alkylating chemotherapy causes hair follicle stem cells to lose their regenerative ability by initially triggering proliferation followed by apoptosis, leading to permanent regeneration loss.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study found that in vitro treatments with 5alpha-reductase inhibitors and androgen receptor antagonists strongly stimulate VEGF expression in dermal papilla cells.

This study found that β-sitosterol, a brain-penetrable phytosterol, reduced melanoma cell growth and brain metastasis formation by interfering with mitochondrial respiration, suggesting its potential as an adjuvant therapy to BRAF inhibitors for patients with melanoma brain metastases.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

This study found that forsythiaside-A, a natural compound from Forsythia suspensa, was more effective than finasteride at preventing apoptosis of hair cells and delaying the catagen phase entry in an androgenic alopecia mouse model.

This review explores how low-energy He-Ne laser therapy may stimulate repigmentation in vitiligo by affecting mitochondrial pathways and melanocyte function, but does not report new clinical results.

This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

This review examines how caloric restriction could promote autophagy to rejuvenate aging stem cells, though the precise molecular mechanisms remain unclear.

In this study, applying FGF-2-containing dalteparin/protamine nanoparticles to the scalp was associated with a significant increase in hair diameter over six months among participants with thin hair.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This study concluded that the new subfractionation culturing method generates highly homogeneous adipose-derived stem cells with enhanced mitogenic, paracrine, and hair growth-promoting effects compared to traditional isolation methods.

This study found that minoxidil stimulates the Kir6.2/SUR2 potassium channel, leading to tumor growth arrest in an ovarian cancer xenograft model by disrupting mitochondrial function and inducing cell death.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

This study found that asebic mice exhibit abnormal sebaceous gland differentiation and insufficient sebum production due to defective regulation of cell processes, despite possessing normally developing sebaceous glands initially.

This review discusses the concept of drug repositioning and highlights fragmin and protamine as emerging biomaterials for tissue engineering and regenerative medicine, but it reports no new clinical results.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

This study found that mice lacking myelin protein zero-like 3 (Mpzl3) had reduced body weight and adiposity despite increased food intake, which was linked to higher energy expenditure and improved glycemic control.
