This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that a gintonin-enriched fraction from ginseng promoted hair growth in mice by stimulating dermal papilla cell proliferation and increasing hair follicles and weight.

This study found that androgen receptor signaling is linked to blood vessel regression in the dermal papilla of balding scalp, contributing to hair follicle miniaturization in androgenetic alopecia.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.

This study explored the anti-hair loss potential of plant extracts like licorice, salvia miltiorrhiza, and others, finding they increased ALP and β-catenin expression and reduced TGF-β1 and IL-6 in human dermal papilla cells without cytotoxicity.

In this study, researchers developed a 3D-printed vascular model to analyze how different shear stresses influence cell behavior and promote cellular organization around neovessels, offering insights into tissue engineering for wound reconstruction.

N,N-Dimethylglycine sodium salt may improve skin health and treat hair loss.

In this study, researchers used 3D bioprinting to successfully create engineered skin tissues with hair follicle-like structures, potentially enhancing skin grafts and safety testing for chemical compounds by more closely mimicking natural skin complexity.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This study found that CTHRC1 is crucial for sweat gland function and vascular network integrity in mice, and its administration improved sweat gland performance by reconstructing nearby blood vessels.

Minoxidil boosts hair growth by targeting adenosine and possibly sulfonylurea receptor 2B.

This study found that topical cilostazol promotes hair growth, enhances hair follicle activities, and may serve as a potential treatment for alopecia.

This study found that a solution containing 0.5% Camellia japonica placenta extract increased scalp moisture and reduced sebum content, dead keratin, and erythema in adult females, suggesting potential as a scalp treatment.

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 study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This study demonstrated that enhancing human skin constructs with hair follicles through engineered cell organization and vascularization improved hair growth in immunodeficient mice, suggesting potential advances for treating alopecia and chronic wounds.

This study suggests that human dermal papilla cells respond to hypoxia by increasing the expression of HIFs, TGF-β2, and BMP4, which may influence hair cycle regulation.

This study found that salvianolic acid B significantly enhanced hair growth and delayed hair follicle cycle progression in mice and human hair models, suggesting potential as a treatment for hair loss.
