This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This study utilized a pigmented human epidermal equivalent model to incorporate melanocytes into the epidermis and found enhanced differentiation potential compared to conventional in vitro systems, reflecting in vivo cellular trajectories and highlighting melanocyte-to-keratinocyte communication pathways.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

This study reports that extracellular microvesicles isolated from stimulated dermal fibroblasts enhanced hair follicle growth ex vivo and identified norrin as a novel modulator in hair regeneration processes.

This article outlines the diverse range of topics covered by the Dermatologic Surgery journal and highlights its role as a key resource for experts in cosmetic and reconstructive skin surgery.

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

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

This review discusses the role of miRNA/mRNA regulatory networks in skin development, epidermal homeostasis, and tissue remodeling, and suggests potential for miRNA-based therapies in treating skin conditions, but reports no new clinical results.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This review discusses the functions and potential therapeutic targeting of TRP ion channels in the skin, noting their involvement in both physiological processes and various pathological conditions, but reports no new experimental results.
