This study found that mesenchymal stem cells mainly promote skin regeneration and delay aging through paracrine activity, releasing growth factors and cytokines that protect against oxidative stress and stimulate healing.

This study revealed that basement membrane dynamics are crucial to hair follicle development, influencing progenitor cell behavior and cell division patterns in developing mouse hair follicles.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

This review compiles existing research on infrared radiation's effects on human skin, noting both its potential harmful thermal impacts and encouraging therapeutic applications, but reports no new clinical results.

This review discusses the potential of ginseng and its metabolites for treating hair loss and reports no new clinical findings.

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

In this study, researchers created a hydrogel that reduces oxidative stress and releases a pro-angiogenic drug in response to enzyme activity, which accelerated healing and improved tissue regeneration in chronic diabetic wounds during in vivo experiments.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

This study reported that Moracin M, a compound from the Moraceae family, significantly promoted hair growth and vascular regeneration by enhancing cell proliferation and Wnt signaling activation in laboratory settings, suggesting it may offer a promising alternative to existing hair growth treatments like minoxidil.

This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.

The study identified increased IL-24 expression in keratinocytes and fibroblasts exposed to particulate matter, contributing to skin aging by promoting conditions similar to age-related changes such as increased MMP1 expression and decreased type I collagen production.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

In this review, the authors reported that sprout extracts, rich in bioactive compounds, show promising effects on skin health, such as enhancing collagen synthesis, improving hydration, and reducing inflammation, though most evidence comes from laboratory and animal studies.

In a laboratory study, Grateloupia elata extract demonstrated antioxidant and anti-aging effects by scavenging free radicals, inhibiting collagenase and elastase, increasing procollagen production, and reducing MMP-1 secretion, suggesting its potential use in functional cosmetics.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

This research observed that Salvianolic acid B (Sal B) significantly promoted hair regeneration in vivo and in vitro, outperforming minoxidil in a mouse model of androgenetic alopecia, by activating Wnt/β-catenin and mTORC2/Akt pathways and upregulating MMPs and MAPKs.

Light skin shows more inflammation from sun exposure than dark skin.

This study explores the use of in silico methods to identify potential diagnostic biomarkers for primary cicatricial alopecia, revealing significant interactions among genes and proteins related to disease pathogenesis.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

This article discusses the structure and function of the skin's epidermis, detailing its role as a protective barrier and nutrient exchange system, without presenting new research findings.

This review discusses the various biological activities of Epigallocatechin Gallate (EGCG) and its potential uses in cosmetics, food, and medicine, without reporting new clinical findings.

This article suggests that zinc-dependent factors may play a role in the regulation of the hair follicle cycle and could be involved in the pathogenesis of alopecia areata, but experimental confirmation is needed.

This review explores the skin regeneration process in spiny mice and highlights differences from laboratory mice, focusing on potential molecular and immune system roles without reporting new experimental results.

This study found that topically applied melatonin exerts significant anti-aging effects on human scalp skin ex vivo, including increased SIRT1 expression and reduced mTORC1 pathway activity.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This review discusses the roles of various growth factors and cytokines in skin regeneration, highlighting their potential for future therapeutic development, and reports no new experimental findings.

This paper explores the relationship between the dermal extracellular matrix and cutaneous malignant melanoma, suggesting that ECM involvement may play a key role in the cancer's growth, invasiveness, and initial metastasis.

This study reports that a prototype device may accurately measure changes in hair quantity, diameter, and density in patients with balding by assessing the cross-sectional area of hair bundles.

In this study, researchers found that psoriasis patients with untreated lesions showed increased activation of defensins, matrix metalloproteinases, and neuropeptides, which may be stimulated by specific inflammation pathways.

This study found that in rats, combined treatment with finasteride and doxazosin altered epithelial cell behavior and matrix metalloproteinases activity, suggesting effects possibly mediated by TGF-β1 and androgen pathways.
