January 1994 in “Differentiation” Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.
129 citations,
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.
127 citations,
January 2015 in “Journal of Biological Rhythms” The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
127 citations,
January 2013 in “PLOS ONE” Probiotic bacteria improved skin and hair health in aged mice.
127 citations,
July 2002 in “EMBO journal” Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.
125 citations,
August 2020 in “Frontiers in Immunology” Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.
125 citations,
September 2001 in “The FASEB Journal” Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.
124 citations,
February 2018 in “Nature Reviews Genetics” Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
123 citations,
November 2012 in “Stem cells” MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.
120 citations,
November 2014 in “Biological Reviews” The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
118 citations,
January 2016 in “Current Topics in Developmental Biology” The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.
117 citations,
August 2019 in “Drug Design Development and Therapy” Minoxidil effectively treats hair loss, but use cautiously and monitor side effects.
117 citations,
March 2017 in “Nature Communications” Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.
117 citations,

116 citations,
May 2013 in “Proceedings of the National Academy of Sciences of the United States of America” Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
111 citations,
January 2007 in “Seminars in cell & developmental biology” Hair, teeth, and mammary glands develop similarly at first but use different genes later.
111 citations,
March 1951 in “Annals of the New York Academy of Sciences” Understanding the mouse hair cycle is crucial for cancer research.
