In this study, various types of minor hair follicle damage were observed during follicular unit extraction, with paring and hair bulb injury being more apparent under microscopic examination.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical 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 review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

Hair growth is cyclic and influenced mainly by local factors.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

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

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

The researchers described a chip-based bioreactor platform for dynamic perfusion, which may enhance in vitro skin models by introducing mechanical shear stress and extending culture periods.

Androgens can cause hair growth in some areas and hair loss on the scalp.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

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 indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.
