This study suggests that porphyra-334 may have antiaging properties, promoting collagen synthesis, improving periorbital wrinkles, and supporting hair follicle growth through gene regulation.

This study found that basal cell carcinoma cells differentiate along hair follicle lineages and may be influenced by hair follicle cycle modulators for potential therapeutic targeting.

This study found that applying glycosaminoglycans fractions from ascidian tunics stimulated human follicle dermal papilla cell proliferation and, when used on mice hair for 28 days, produced a hair growth effect comparable to Minoxidil.

This study found that a developed nanostructured lipid carrier formulation of tea seed oil can effectively stimulate hair growth and reduce the oily feeling associated with direct application.

This study found that expanding hair follicle keratinocytes with a fibroblast feeder followed by short-term coculture with dermal papilla cells could restore their ability to form new hair follicles.

This study investigated bovine milk-derived exosomes and found they significantly increased dermal papilla cell viability and up-regulated WNT pathway components in human hair follicles, suggesting potential therapeutic value for hair loss disorders like androgenetic alopecia and telogen effluvium.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study explores ear pinna development in mice and reports that elastic cartilage formation is disrupted in a short ear mutant, correlating with increased adult adipocytes and impaired chondrogenesis.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.

This study developed an in vitro artificial hair germ model using dermal papilla cells and skin keratinocytes to explore early stages of hair follicle regeneration.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

In this study, using stirred-suspension bioreactors to expand dermal stem cells resulted in larger numbers, but had reduced efficiency in forming hair follicle structures compared to static culture conditions.

In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.

Ursolic and shikimic acid together boost hair growth better than alone.

This review highlights the therapeutic potential of hair follicle stem cells in tissue repair and hair regeneration, discussing the molecular mechanisms and the impact of natural compounds on stem cell properties, which may support the development of novel hair loss treatments.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This review of murine studies reports that γ-rays affect hair follicle pigmentation in mice throughout the hair cycle, while effects on hair structure may be obscured by aging.

In this study, Ageratum houstonianum ethanolic extract and its active component agerarin were found to promote hair growth and follicle elongation by increasing SCUBE3 expression via activation of MAPK–AP-1 signaling in human dermal papilla cells, suggesting potential therapeutic value for treating hair loss.

This study investigated the use of Minoxidil encapsulated in HA-PLGA nanoparticles for alopecia treatment and found that these nanoparticles efficiently delivered the drug to hair follicle cells without significant cytotoxicity, offering a potential transdermal delivery method for various diseases.
