This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This study found that hexane extracts of Nostoc verrucosum significantly inhibited melanin synthesis in melanoma cells and demonstrated antioxidant activity, suggesting potential use in developing cosmetic and functional food products.

This study found that transgenic expression of Endothelin 3 in mice can maintain a dark pigmentation phenotype independently of Mc1r signaling by regulating melanogenic genes.

This study suggests that typical skin lesions in Carney complex may originate from the pro-melanogenic activity of a specific dermal fibroblast population influenced by PKA signaling.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.

This study found that Plerixafor, a CXCR4 antagonist, promotes melanogenesis in melanocytes by increasing MITF and tyrosinase expression and enhancing melanocyte migration, and it effectively restores pigmentation in a mouse depigmentation model without toxicity, highlighting its potential for treating pigmentary disorders.

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.

This study found that enhanced expression of the Sonic hedgehog gene via an adenovirus vector accelerated hair regrowth in mice with chemotherapy-induced alopecia.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

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.

In this study, researchers observed that in barn owls, the relationship between black feather spot size and testosterone levels varied by age and sex, suggesting involvement of genes regulating both traits rather than direct influence of testosterone on feather coloration.

This study found that the green alga Botryococcus terribilis and its novel compounds significantly promoted hair growth marker gene expression in hair follicle dermal papilla cells without cytotoxic effects.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This study concluded that lenalidomide significantly induces the proliferation and migration of melanocyte stem cells, enhancing their differentiation into functional melanocytes in a mouse model.

In this study, researchers developed a promising transdermal agent using Triton X-100-modified polyethyleneimine that successfully delivered genetic material to hair follicle cells in mice, potentially alleviating hair loss due to androgenetic alopecia by promoting cell proliferation and inhibiting apoptosis.

This study found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This study found that miRNA-24 downregulates the KLF6 gene, influencing coat color by affecting melanogenesis pathways in Cashmere goats, and that miRNA-24 inhibition increased melanin content in mice.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

This literature review reports that mutations in the SASH1 gene are linked to different pigmentation disorders, including dyschromatosis universalis hereditaria and lentiginosis. It further suggests SASH1's significant role in melanocyte processes and its potential as a target for developing treatments for these conditions.

This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

In this study, modulating Tyrosinase expression altered mouse coat color by affecting melanosome accumulation, indicating that melanosome maturity plays a role in determining skin and hair color beyond total melanin content.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study suggests that apigenin may stimulate hair growth by downregulating TGF-ß1 gene expression in human epidermal keratinocytes and promoting hair follicle elongation in a rat hair follicle culture.

This study found that extracts from Hom Thong banana peels, rich in phenolic compounds, may inhibit melanin production in human and mouse melanoma cells, showing potential as anti-melanogenic agents comparable to standard treatments like arbutin and kojic acid.
