research BMP4 regulates differentiation of nestin-positive stem cells into melanocytes
BMP4 helps stem cells turn into pigment-producing cells, affecting hair color and growth.
research Transgneic Endothelin 3 Regulates Murine Pigment Production and Coat Color
The gene Endothelin 3 makes mice's fur darker by increasing pigment cells and pigment levels.
research Paracrine Secreted Frizzled-Related Protein 4 Inhibits Melanocytes Differentiation in Hair Follicle
A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.
research The Psychology of Gray Hair
Stress can cause hair to turn gray by depleting pigment-producing cells through the release of a stress hormone.
research Hair regrowth in alopecia areata and re‐pigmentation in vitiligo in response to treatment: Commonalities and differences
Hair regrows faster in alopecia areata than skin re-pigments in vitiligo due to differences in stem cells and treatment effects.
research Human Epidermal Neural Crest Stem Cells (hEPI-NCSC)—Characterization and Directed Differentiation into Osteocytes and Melanocytes
Human epidermal neural crest stem cells can become bone and skin pigment cells, making them useful for therapies.
research Stingless bee propolis promotes hair follicle regeneration and melanocyte function in chemotherapy-induced alopecia mouse model
Stingless bee propolis may help regenerate hair follicles and improve pigment function in chemotherapy-induced hair loss.
research Coordinated Activation of Wnt in Epithelial and Melanocyte Stem Cells Initiates Pigmented Hair Regeneration
Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.
research A randomized pilot study to compare hair follicle cell suspensions prepared using trypsin alone versus trypsin in combination with collagenase type I for transplantation in vitiligo
Adding collagenase to trypsin improves cell yield and repigmentation in vitiligo treatment.
research Rippled‐pattern trichomatricoma
A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.
research Actions of isotretinoin and etretinate on the pilosebaceous unit
Isotretinoin shrinks sebaceous glands without affecting hair or skin color, unlike etretinate.
research Tyrosinase Depletion Prevents the Maturation of Melanosomes in the Mouse Hair Follicle
Reducing Tyrosinase prevents mature color pigment cells from forming in mouse hair.
research Wnt10b Promotes Differentiation of Mouse Hair Follicle Melanocytes
Wnt10b helps hair follicle cells mature and produce pigment.
research Culturing of Melanocytes from the Equine Hair Follicle Outer Root Sheath
Researchers successfully grew horse skin cells that produce pigment from hair follicle samples.
research Ultrastructural abnormalities in the dermal papillae of both lesional and clinically normal follicles from alopecia areata scalps
Alopecia areata affects hair follicle structure, even in non-balding areas.
research The Hair Pigmentation Unit and Hair Graying
Hair color is due to active pigment cells in hair during growth.
research Histologic features of alopecia areata other than peribulbar lymphocytic infiltrates
Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Splenic eumelanin differs from hair eumelanin in C57BL/6 mice.
Splenic eumelanin in C57BL/6 mice is different from hair eumelanin.
research α3β1-integrin regulates hair follicle but not interfollicular morphogenesis in adult epidermis
α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.
research Tfap2b specifies an embryonic melanocyte stem cell that retains adult multi-fate potential
The gene Tfap2b is essential for creating a type of stem cell in zebrafish that can become different pigment cells.
research 1363 Hair follicle growth and pigmentation during ageing
The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.
research Effects of the selective TrkA agonist gambogic amide on pigmentation and growth of human hair follicles in vitro
Gambogic Amide helps maintain hair color and promotes hair growth.
research Photoaggravation of hair aging
Sunlight exposure ages hair, making it brittle, stiff, and dry.
research 558 The Bacterial Metabolite, Butyrate, Prolongs Anagen and Promotes Autophagy, Mitochondrial Activity, Melanogenesis and Antimicrobial Peptide Production in Human Scalp Hair Follicles
Butyrate helps hair grow longer, improves hair cell health, increases pigment production, and boosts hair's natural defenses.
research Mysteries of salt and pepper
Preventing hair graying may be possible by managing oxidative stress and activating melanocyte stem cells.
research Biology of melanocytes in mammals
Melanocytes are important for skin and hair color and protect the skin from UV damage.
research Sox2 in the dermal papilla regulates hair follicle pigmentation
Sox2 controls hair color by affecting pigment production in hair follicles.
