This study suggests that gamma-ray irradiation affects hair follicle density, structure, and pigmentation in mice, with some changes observed in later hair cycles.

This study reviewed existing literature and reported two cases of perinevoid alopecia, suggesting that melanocyte antigens may be involved in its development.

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

In this study, researchers found that in adult mice, new hair follicles with pigmentation can regenerate from the epidermis after skin wounding, aided by melanocyte stem cells moving from nearby existing hair follicles.

This review discusses the interactions and signals affecting skin stem cells and their environments but reports no new experimental results; the authors highlight the need for understanding these processes to enhance tissue rejuvenation and repair.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This report suggests that in vitiligo, melanocytes may be destroyed by the same factors necessary for melanin production, contributing to the skin's depigmentation.

This study reports that treatment with X-rays or procarbazine induced dose-dependent mutations in melanocytes in mouse hair follicles, showing similar mutation rates to previous methods.

In this study, researchers observed that in mice, as they age beyond 200 days, unusual curved hair follicles and increased white hairs emerge, indicating stem cell-related changes in keratinocyte and melanocyte characteristics, providing insights into hair aging processes.

This study found that early pigment cell markers Sox10 and c-KIT, as well as DCT/TRP-2, were detectable in melanogenically-active melanocytes of the anagen bulb in human hair follicles.

This study found that hair follicle melanocytes show increased age-related susceptibility to oxidative stress compared to epidermal melanocytes, which may contribute to the graying of hair.

This review highlights the complexities of hair graying and the limitations of current models to fully replicate hair follicle pigmentary unit function, suggesting that technologies like organoids and bioprinting show promise but require further development for effective hair repigmentation interventions.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This study investigated the pigments and cells causing discoloration in stasis dermatitis but did not clarify the role of melanin or melanocytes in this condition.

At a workshop highlighted during the 2025 ESPCR meeting, researchers discussed the challenges and variability in culturing skin-related cells, identifying key factors such as media composition and species differences that affect experimental reproducibility, and emphasized the importance of transparent practices to advance pigment cell research.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This review discusses various skin diseases with endocrinological origins and reports no clinical results, highlighting the need for interdisciplinary understanding in diagnosis.

This case report describes a man's permanent skin and hair whitening, and generalized anhidrosis following allogeneic stem cell transplant, linked to immune-mediated destruction of melanocytes.

This article reviews dermatological research on black skin, emphasizing its unique physiological characteristics and common conditions like acne and eczema, and suggests more focus is needed on its structural differences and clinical responses.

A young man was unexpectedly diagnosed with basal cell carcinoma after a scalp examination and confocal microscopy.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

The FTO gene hinders stem cells in hair follicles from becoming pigment cells.

COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem cells.

This study demonstrated that novel curcumin analogs CMC2.24, CMC2.23, and CMC2.5 were more effective and less toxic than parent curcumin in inhibiting melanin production in normally pigmented human melanocytes, suggesting potential for skin depigmentation therapies.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

Using mouse hair follicle organoids, this study demonstrated that BMP4 plays a key role in controlling hair follicle coloration and growth, as well as directing Nestin-positive stem cells towards becoming melanocytes, the pigment-producing cells responsible for hair color.
