This study found that Wnt7a-containing conditioned medium from UC-MSCs can accelerate wound healing and promote hair follicle regeneration by enhancing specific cellular functions in the wound microenvironment.

This review discusses chemotherapy-induced alopecia, highlighting its pathogenesis, clinical patterns, and current therapeutic approaches, with no new clinical results reported.

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.

This study developed a rapid method to extract proteins from human hair, revealing phosphorylation on serine and threonine residues in alpha-keratins and matrix proteins.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

Minoxidil enhances hair growth and preserves the root sheath in cultured follicles.

This study found that hypothermically stored amniotic membrane grafts promoted greater tissue regeneration, including basket-weave collagen matrix and follicle formation, compared to dehydrated amnion/chorion meshed grafts in a rat wound model.

This review found that microneedling can stimulate various biological pathways to promote tissue remodeling, enhance skin regeneration, and benefit conditions like wound healing and skin rejuvenation, with emerging uses in targeted drug delivery and periodontal therapy.

This study discusses how polynucleotide-based cosmetic products can improve aging skin in patients with particular morphotypes by restoring cellular metabolism, enhancing microcirculation, and promoting intracellular matrix remodeling, offering potential benefits for reversing chrono- and photo-aging and aiding tissue recovery after cosmetic or surgical procedures.

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.

In this study, activated PRP injections appeared to promote hair growth in AGA-affected scalp skin transplanted onto mice, compared to non-activated PRP.

In this study, red ginseng extract and its ginsenosides enhanced human hair follicle cell proliferation and countered dihydrotestosterone-induced suppression, suggesting potential to promote hair growth.

This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This review highlights recent advances in chitosan-based nanoparticles (CS NPs) for drug delivery, discussing their modifications, preparation methods, production with organic and inorganic materials, and their latest implementations in the field, emphasizing the role of CS NPs in improving drug transport and release properties.

This review discusses the anatomical and histological characteristics of facial fat compartments and reports no new clinical results, emphasizing a need for further research on their role in facial aging.

In this laboratory study, ASC-conditioned medium showed higher therapeutic potential than extracellular vesicles alone in reducing inflammation and catabolic activity in human chondrocytes with an osteoarthritis phenotype, highlighting its possible use in osteoarthritis management.

This study suggests that IL-1β produced by dermal papilla cells, regulated by protein kinase C, may inhibit human hair follicle growth through paracrine signaling.

This study found that electrospun short fibrous sponges effectively mimic the 3D extracellular matrix, promoting tissue regeneration, angiogenesis, and wound healing in diabetic rats better than 2D fiber membranes.

This study found that the Ovol2-Zeb1 regulatory circuit is crucial for controlling directional migration and proliferation in epithelial cells, facilitating skin regeneration and repair in mice.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.
