This study found that tectoridin, an isoflavone from Rhizoma Belamcandae, may stimulate hair growth by activating Wnt signaling in human and mouse cell cultures.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

Using synchrotron X-ray imaging, this study mapped the complex innervation of male rat vibrissa follicles, revealing distinct types of myelinated afferent neurons and patterns of axonal organization that may inform sensory processing in the brainstem.

This study suggests that keratin 15 and Id3 proteins play distinct roles in epithelial and dermal cell activities during the regeneration stages of rat vibrissae hair follicles.

This study described the diverse vibrissal follicle anatomy in fetuses of three cetacean species and observed species-specific differences, supporting further investigation into vibrissal form and function across cetaceans.

This study found that a 70% methanol extract from red ginseng stimulated hair growth in mouse vibrissal follicles, suggesting its bioactive components, particularly certain ginsenosides, may promote hair growth.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

Minoxidil works in liver and outer hair root sheath for hair growth.

This study found that water-soluble extracts of Illicium anisatum promoted hair follicle elongation in cultured mouse vibrissae, suggesting potential use in hair growth products.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

This study found that nestin-driven GFP labels blood vessels originating from hair follicles in mice, which could be used to study early events in skin angiogenesis and for antiangiogenesis drug screening.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

This study found that leptin from dermal white adipose tissue may regulate hair growth and cycle progression through its receptor on hair follicle epithelium in mice and humans.

This study found that Activin B at 10 ng/mL may promote vibrissae follicle growth in mice by enhancing hair matrix cell proliferation and cell cycle progression via ERK signaling pathways.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This study observed that HAP stem cells from the whiskers of young mice near the ear differentiated into heart-muscle cells more efficiently than those from older mice or other whisker locations.

In this study, KY19382 was observed to promote hair regeneration and de novo hair follicle formation in mice by activating Wnt/β-catenin signaling, suggesting its potential as a therapeutic for alopecia.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This study found that dermal papilla cells and bulge stem cells can potentially be used to reconstruct hair follicles, as hair follicle-like structures were observed after culturing under a rat's renal capsule.

In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.

This study found that hair follicle stem cells from mice can differentiate into beating cardiac muscle cells, suggesting potential applications for heart regeneration in regenerative medicine.
