Scientists now have used stem cell technology to successfully create melanocyte precursor cells that can be used in research on melanoma and other pigment cell-related illnesses.
" The idea behind it is to re-pigment your hair with your own natural color.Welsh explained that gray hair is caused by a melanocyte deficiency.
The answer lies in a special type of cell known as a melanocyte, which produce melanin pigments as they grow into the hair fibre.
Hair has colour because of cells called melanocyte, which produce melanin pigments.
Additionally, Fontana-Masson staining and immunolabeling allowed visualization of dendritic melanocyte protrusions into suprabasal epidermal layers.
"Scientists have long known that in order to prevent hair from going grey they would need to either prolong the life of the melanocytes in the hair bulb -- by protecting them from injury -- or expand the melanocyte stem cell reservoir in the upper or top region of the hair follicle so they continue to replace lost pigment cells,"explainedRodney Sinclair, Professor of Dermatology, Epworth Hospital, at the University of Melbourne.
Harris said melanocyte stem cells were essential to hair color as they produced the melanocytes that were responsible for making and depositing pigment into the hair shaft.
KIT also plays a pivotal role in melanocyte migration, development and proliferation (Grichnik, 2006).
The origin of the melanoma precursor cell is open to debate, but it is most probably a tissue-specific stem/progenitor melanocyte that over time has acquired cytogenetic and epigenetic alterations and has ultimately undergone malignant transformation.
Approximately, 10% of genes within or near these loci encode melanocyte proteins.
When melanocytes are exposed to oxidative stress, however, melanogenesis is inhibited because the melanogenic enzymes or melanocyte differentiation markers TYR, TRP1, and DCT and the melanogenesis master regulator MITF [15] are downregulated.
Wnt/[beta]-catenin signaling pathway [13,14] plays important roles in melanocyte development and differentiation.
