In this study, researchers found that alopecia areata patches with white hair follicles showed a significant decline in Sox10 marker expression compared to patches without white hairs, while other melanocytic markers were similarly expressed in both groups.

This article reviews advancements in understanding skin regeneration and suggests that bioengineering skin surrogates may soon enhance treatments for skin trauma, but it presents no new clinical findings.

This study identified key components of melanocyte stem cell niches that maintain stem cells in a dormant state and established a culture system that potentially replicates some aspects of in vivo stem cell activity.

This study found that the cytoplasmic dynein component Dynlt3 is essential for effective melanosome transport and transfer in mouse melanocytes, linking melanosome positioning and acidity to the Wnt/β-catenin signaling pathway.

This review discusses the advancements and challenges in developing in vitro human skin models incorporating components like vasculature for drug testing and disease research, but reports no new clinical results.

In this study, researchers presented cases of cellular neurothekeoma in three male family members with early-onset in infancy, suggesting a potential genetic component and inheritance pattern, which deviates from the typical presentation seen mostly in women between 20–30 years.

In this study, chronic stress signals were found to delay hair follicle stem cell activation and negatively impact their niche components in rodents.

This study in mice found that butin, a component of Vernonia anthelmintica, increased melanin production and related proteins while reducing oxidative stress markers in a model of hydroquinone-induced vitiligo, suggesting support for its traditional use against this condition.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.
