In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

In this study, the methanol-ultrasound extract of Dendropanax morbifera leaf showed potential for use in functional cosmetics and hair growth products due to its high antioxidant capacity and effects on growth factor expression without cytotoxicity.

No genetic link between prostaglandins and hair loss found.

This study observed that using 3D dermal papilla microtissues enhances hair follicle regeneration and gene expression compared to 2D cultures, indicating their potential for hair growth drug screening.

This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study established the R-7 dermal papilla cell line, which retained essential characteristics of primary cells without undergoing malignant transformation, suggesting its potential for future hair research.

This study identified candidate genes related to hair follicle development in Merino sheep, providing insights for improving sheep wool quality and potentially understanding human hair growth mechanisms.

In this study, researchers observed that dysregulated innate lymphoid cells type 1, alongside CD8+ T cells, may contribute to the pathogenesis of alopecia areata by affecting hair follicle health.

This study found that the activity of CD73, an enzyme expressed in the hair follicle epithelium, may regulate human hair growth by modulating adenosine production.

This study reported improvement in hair loss lesions in C3H/HeJ mice with alopecia areata following treatment with the CCR5 inhibitor maraviroc, alongside reduced infiltration of specific T cells in the lesions.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

This article reviews the molecular mechanisms involved in androgenetic alopecia and the androgen's paradoxical role in hair growth, but reports no new experimental findings.

This study suggests that oxidative stress may contribute to androgenetic alopecia by inducing premature senescence and secretion of hair growth inhibitors in dermal papilla cells from balding scalp.
