In this study, researchers used a mouse model to identify an adipocyte-to-fibroblast conversion pathway that promotes mast-cell recruitment and dermal fibrosis in atopic dermatitis, suggesting a potential therapeutic approach to block this process and reduce inflammation and fibrosis.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This study found that PDGF-BB affects human melanocytes differently depending on their differentiation stage, stimulating melanoblast proliferation but inhibiting melanocyte proliferation while promoting their differentiation.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This review discusses the role of melanocyte stem cells in skin pigmentation and potential regenerative therapies, but reports no new clinical results.

This study found that HDAC6 plays a crucial role in regulating primordial follicle activation, with its overexpression delaying activation and preserving fertility by reducing NGF levels.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

In this study, researchers identified a new dominant mutation in Hairless mice, called Pied, resulting from a deletion in the Adam10 gene, which causes freckle-like skin pigmentation by inhibiting melanocyte expansion.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

In this study, researchers using single nuclei RNA-sequencing found that fibroblasts in deeper layers of mouse skin expressed higher levels of pro-inflammatory genes post-wounding compared to other cells, highlighting their significant role in early inflammation and tissue repair processes.

This study found that Dermal Fibroblast Progenitors have repressed chromatin profiles which hinder their ability to reform skin in allograft assays despite their differentiation potential.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This review reports the first known case of hair repigmentation associated with lamivudine use and examines mechanisms related to drug-induced hair repigmentation, suggesting potential therapeutic strategies for reversing hair graying.

This study found that overexpression of β-catenin in bipotent Schwann-cell precursors promotes melanocyte development in limb areas by inducing MITF and repressing FoxD3, especially during a specific developmental timeframe.

In this study, researchers observed that dormant TRP-2+ melanoma cells in bone marrow can interact with CD8+ T cells in tumor-bearing ret transgenic mice, potentially influencing immune responses.

This study identified a novel SCF mRNA splice variant in white merino sheep skin, which may play a role in hair follicle melanogenesis.

This review explored the causes of hair graying and evaluated how plant-derived extracts and phytochemicals might alleviate it, noting that certain compounds showed potential in enhancing melanocyte function, reducing oxidative stress, and influencing stress-related pathways based on experimental evidence.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

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

This study found that fibroblasts from Emery-Dreifuss muscular dystrophy patients with certain genetic mutations overexpress markers of fibrosis, and gene correction techniques reduced fibrogenic molecule expression in cell models, suggesting potential therapeutic applications.

This study found that nestin-expressing cells in the hair follicle bulge exhibit multipotent stem cell-like properties and can generate neural cells both in vitro and in vivo.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

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 found that examining hair morphology provides deeper insights than classification, suggesting a potential population stratification artefact between hair curvature and cross-sectional shapes in the examined admixed African-European sample.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

This review discusses the therapeutic applications of Hibiscus rosa sinensis and reports no new clinical results; the authors highlight its potential in herbal medicine.
