This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This article describes how PESCADOR software assists in creating detailed biological pathway charts from PubMed abstracts, focusing on hair and breast development case studies without providing new clinical results.

This study found that astaxanthin effectively protected human dermal papillae cells from oxidative stress induced by hydrogen peroxide, reducing the percentage of cells expressing a stress marker significantly, suggesting potential benefits for hair loss treatment related to reactive oxygen species.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This study suggests that human dermal fibroblasts can be converted into dermal papilla cell-like cells using microencapsulation, which may facilitate hair follicle regeneration in mice without chemical or genetic reprogramming.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study found that in a population of hair follicles, regenerative cycling stages are regulated by both intrinsic and extrinsic signals, with WNT/BMP signaling mediating interactions among follicles for adaptability.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

This study found that balding dermal papilla cells show premature senescence and altered expression of stress and DNA damage markers, suggesting sensitivity to environmental stress in androgenetic alopecia.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.
