May 2015 in “Cell Stem Cell” Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
113 citations,
March 2018 in “Biological reviews/Biological reviews of the Cambridge Philosophical Society” Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.
113 citations,
November 2017 in “Scientific Reports” Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.
108 citations,
November 2006 in “Phytomedicine” Green tea component EGCG could potentially promote human hair growth.
105 citations,
January 2010 in “Mediators of Inflammation” Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.
105 citations,
February 1996 in “Journal of biological chemistry/The Journal of biological chemistry” The TGM3 gene's promoter region is key for skin and hair cell function and may aid gene therapy.
103 citations,
November 2014 in “Journal of Cell Biology” MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.
103 citations,
January 2006 in “Journal of Cell Science” The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.
