Abstract 81

In this viewpoint, researchers discussed the possible role of the developmental origin of scalp dermis in influencing the specific pattern of hair follicle miniaturization seen in male pattern hair loss, noting that frontal follicles are more susceptible while occipital follicles remain largely terminal.

The researchers identified differences in gene expression between fetal and adult dermal papilla cells that could explain fetal cells' ability to regenerate hair follicles, while adult cells lack this capacity.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

In this study, low-level light therapy increased the proliferation and activation of dermal papilla cells, which in turn may enhance the growth of outer root sheath keratinocytes, suggesting potential mechanisms for improving hair follicle interaction.

This article describes the anatomy and life cycle of hair follicles, explaining how disruptions in the hair growth cycle can lead to various forms of alopecia.

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.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.
