This review discusses the skin side effects associated with targeted cancer therapies and reports no new clinical results; it emphasizes the need for empirical management based on expert opinion.

This study found that in Chinese goat breeds, specific genetic variations, particularly in Tibetan Cashmere goats, are associated with traits like hair growth and adaptation to high-altitude environments.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

This study found that stable regeneration of pigmented hairs in mice after severe wounding can occur when the wound is made during the anagen stage, influenced by Wnt and Kit signaling pathways.

This study examined cashmere goats using whole-genome resequencing data and found that the Inner Mongolia cashmere goat had the lowest inbreeding coefficient, with genes identified linked to fiber, fertility, disease resistance, and growth, which can inform future breeding efforts.

This study found that Hetian sheep with higher wool density produce more and finer wool, with key genes potentially influencing their wool growth and density.

Keratinocyte cytokines and genetic variations influence the development of moles and skin pigmentation.

Harris et al. describe a new mouse model for vitiligo, where interfollicular melanocytes are retained and melanocyte-targeting immune responses are simulated, aiding the development of immunomodulatory therapies.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

This study found that inhibiting prolactin secretion during the telogen phase can reduce the number of activated secondary hair follicles and the width of hair bulbs.

This research examined the transcriptional landscape of quiescent melanocyte stem cells (qMcSCs) in adult female mice, revealing significant heterogeneity within this cell population and identifying novel subpopulations that vary in immune privilege regulation, melanocyte differentiation potential, and neural crest potential.

This study reports that in mice, retinoic acid mediates communication between hair follicle and melanocyte stem cells by influencing differentiation in their shared niche during hair regeneration.

This chapter reviews the skin side effects associated with targeted cancer therapies and emphasizes the importance of collaboration between oncologists and dermatologists without reporting new results.

This study found that transfecting alpaca melanocytes with miR-5110 altered gene expression related to pigmentation, specifically identifying pathways like MAPK and Wnt as involved in melanogenesis regulation, providing insights into miR-5110's role in pigmentation processes.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study suggests that the paradoxical effects of androgens on hair growth are due to differential gene expression in hair follicles, possibly established during embryogenesis.

Imatinib can repigment grey hair, while SU11428 can cause temporary hair depigmentation.

This study suggests that different melanocyte subpopulations in hair follicles have varying patterns of apoptosis and survival during the catagen phase, which may inform models for modulating melanocyte behavior in vivo.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

This study found that methanol is more effective than isopropanol at removing external cortisol from grizzly bear hair and suggests that the choice of solvent can influence hair cortisol concentration results.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

This study found that a spermidine-based nutritional supplement increased the number of anagen phase hair follicles in healthy humans, suggesting potential benefits for hair loss conditions.

This report describes two cases of white piedra caused by Trichosporon inkin in a northern climate, detailing clinical findings and diagnosis without presenting new experimental results.

This article is a letter to the editor discussing hair graying and loss potentially induced by imatinib mesylate, but it does not provide new research results.

This preliminary study observed that melanoblasts are preserved in the white hair follicles of segmental vitiligo lesions.

The researchers reported that Gambogic Amide may prevent hair greying and promote hair growth by maintaining follicle pigmentation in vitro through activation and migration of melanocytes.
