This study observed that activating the Wnt/β-catenin pathway enhances hair follicle stem cell proliferation and differentiation, promoting hair growth and wound healing, and demonstrated the potential for outer root sheath transplants to aid skin repair, although challenges remain for clinical application.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

In this study, aralia continentalis extract was observed to promote hair follicle development in mice through anagen progression, with the low dose being more effective than the high dose.

In laboratory and artificial skin model experiments, this study found that plant-derived PDRN from Korean ginseng effectively promoted skin cell regeneration and strengthened the skin barrier, suggesting a sustainable alternative to animal-derived PDRN.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study suggests that human outer root sheath cells are suitable for skin replacement, as they can form a stratified epithelium similar to normal epidermis in organotypic cultures.

In this study, researchers explored how hair follicle neural crest stem cell-derived exosomes, particularly those carrying miR-214-3p, promote neurite outgrowth and aid peripheral nerve regeneration, supported by detailed in vitro and in vivo data on nerve repair and functional recovery in rat models.

This study found that SesZen-Bio TM, a proprietary extract from Sesbania grandiflora leaves, increased proliferation of hair cells and hair shaft length in vitro and ex vivo, potentially due to activation of the Wnt/β-catenin signaling and stem cell differentiation pathways.

This review discusses the relationship between vitamin K and osteoarthritis, noting that while lower vitamin K levels are associated with increased osteoarthritis, the effects of vitamin K supplementation on the condition remain unclear due to a lack of clinical trials.

This study reports that EGF at specific concentrations promotes the proliferation and migration of hair follicle ORS cells by activating the Wnt/β-catenin signaling pathway in vitro.

This study found that mesenchymal stem cells sourced from hair follicle outer root sheath showed higher differentiation efficiency and angiogenic potential for vascular graft applications compared to adipose-derived stem cells.

This dataset supports a study suggesting that hair follicle neural crest stem cell-derived exosomes carrying miR-214-3p may promote neurite outgrowth and aid peripheral nerve regeneration in vitro and in vivo.

This study demonstrated the potential of newly fabricated epithelial cell scaffolds to enhance hair regeneration, showing promise for future alopecia treatments.

This study found that topical application of Korean ginseng berry promoted hair follicle development in mice, with a lower dose proving more effective than a higher dose.

This study found that human embryonic and induced pluripotent stem cells differentiated into specific bulge stem cells and successfully formed new hair follicles when transplanted with mouse dermal cells in immunodeficient mice.

This study reports that human hair follicle stem cells express different surface markers than mouse stem cells, facilitating their isolation and potentially aiding in the development of cell-based skin treatments.

This study demonstrated the potential of epithelial cell scaffolds fabricated with various materials for effective hair regeneration, highlighting their promising application in tissue engineering for alopecia treatment.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This study found that topical treatment with Maneb led to delayed epithelial cell degeneration in hair follicles of rats due to apoptosis.

This study found that transplanting hair follicle bulge-derived stem cells in rats enhanced skin regeneration during expansion by differentiating into several skin-related cells and increasing the expression of growth factors.

This study evaluated nanovesicles derived from Polygonum multiflorum roots, finding that they promote dermal papilla cell proliferation and activate β-catenin signaling, which in turn enhances hair shaft elongation in ex vivo cultured human hair follicles, suggesting their potential use for alopecia treatment.

This study developed a bifunctional sodium hyaluronate microneedle patch incorporating glycyrrhizin-loaded dutasteride micelles and mesoporous polydopamine nanoparticles, which effectively inhibited DHT and reduced ROS in hair follicle cells, resulting in significantly accelerated hair growth in vitro and in vivo.

This study found that overexpression of the transcription factor NFIC may enhance the proliferation and differentiation of stem cells from the apical papilla, suggesting its potential role in dentin/root regeneration.

This review discusses the role of jasmonic acid and its conjugates in enhancing plant stress tolerance and balancing growth and defense mechanisms but provides no new experimental data.

This chapter reviews the potential of stem cells from discarded deciduous teeth in regenerative medicine and dentistry, with no new clinical results presented.

This review discusses the preparation and benefits of a botanical hair mask gel made from flaxseed, fenugreek, and rice water, highlighting its effectiveness in promoting scalp health, hair regeneration, and minimizing damage from chemical hair products, as reported by this source.

This study demonstrated that multipotent stem cells in adult mice whisker follicles migrate to produce whisker growth, and that this process requires precise control of stem cell trafficking.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.
