810-840 / 1000+ results research Hair Follicle Stem Cells Maintain the Differentiation Refractory Niche for Co-Occupant Melanocyte Stem Cells by Regulating Retinoid Metabolic Process
Hair follicle stem cells prevent melanocyte stem cells from differentiating by controlling retinoic acid levels.
research Complications and Limitations of Melanocyte Transplantation
Melanocyte transplantation can safely restore skin color, especially in stable vitiligo, but must be chosen carefully based on the disease phase.
research Mechanisms of Hair Graying: Incomplete Melanocyte Stem Cell Maintenance in the Niche
Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.
research Changes in Different Melanocyte Populations During Hair Follicle Involution (Catagen)
Different melanocyte types in hair follicles either survive or die during the catagen phase.
research Improved Cutaneous Wound Healing After Intraperitoneal Injection of Alpha-Melanocyte-Stimulating Hormone
Injecting alpha-melanocyte-stimulating hormone in mice improved skin healing and reduced scarring.
research Exploring the Role of Melanocyte Subpopulations in Vitiligo
A specific group of early-stage melanocytes is reduced in vitiligo-affected skin, which may explain treatment resistance.
research Skin Melanocytes: Biology and Development
The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.
research Melanoblasts' Proper Location and Timed Differentiation Depend on Notch/RBP-J Signaling in Postnatal Hair Follicles
Notch/RBP-J signaling is crucial for proper placement and timing of melanocyte development in hair follicles.
research Expression Patterns of MITF During Human Cutaneous Embryogenesis: Evidence for Bulge Epithelial Expression and Persistence of Dermal Melanoblasts
Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.
research A Rare Repigmentation Pattern in a Vitiligo Patient: A Clue to an Epidermal Stem-Cell Reservoir of Melanocytes?
Repigmentation in vitiligo may come from melanocyte stem cells in the skin.
research Histopathologic Findings of Cutaneous Hyperpigmentation in Addison's Disease and Immunostain of the Melanocytic Population
The study found increased skin pigmentation and variable melanocyte density in a patient with Addison's disease.
research Future Directions in the Treatment of Vitiligo
New treatments for vitiligo may focus on protecting melanocyte stem cells from stress and targeting specific pathways involved in the condition.
research The Early Repigmentation Pattern of Vitiligo Is Related to the Source of Melanocytes and the Choice of Therapy: A Retrospective Cohort Study
Repigmentation patterns in vitiligo depend on melanocyte source, lesion status, and therapy choice.
research Hair Cycle and Hair Pigmentation: Dynamic Interactions and Changes Associated with Aging
As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.
research Long-Term Follow-Up of Leucoderma Patients Treated with Transplants of Autologous Cultured Melanocytes, Ultrathin Epidermal Sheets, and Basal Cell Layer Suspension
Transplantation is effective for stable leucoderma but not for progressive, widespread vitiligo vulgaris.
research Hair Follicle Stem Cells: Walking the Maze
Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.
research Stem Cell Dynamics in the Hair Follicle Niche
Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.
