November 2015 in “International Journal of Radiation Biology” Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.
3 citations,
June 2017 in “International Journal of Radiation Biology” Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.
September 2023 in “Cells tissues organs” Mice skin matures by day 200, leading to aging signs like curved hair follicles and white hairs due to changes in skin stem cells.
November 2013 in “Elsevier eBooks” Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.
April 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” Spiny mice regenerate skin better than laboratory mice due to larger hair bulges, more stem cells, and different collagen ratios.
165 citations,
June 2007 in “European Journal of Cell Biology” 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.
150 citations,
April 1999 in “Dermatologic Clinics” Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.
31 citations,
September 2013 in “Stem Cells” Smad1 and Smad5 are essential for hair follicle development and stem cell sleepiness.
