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,

127 citations,
December 2005 in “Experimental Dermatology” Stress can stop hair growth in mice, and treatments can reverse this effect.
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.
124 citations,
December 2016 in “Pharmaceuticals” TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.
119 citations,
January 2012 in “Nutrition & Metabolism” Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.
117 citations,
March 2017 in “Nature Communications” Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.
113 citations,
July 2020 in “Communications biology” Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.
108 citations,
July 2004 in “American Journal of Pathology” Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.
107 citations,
December 2013 in “International Journal of Dermatology” The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
106 citations,
January 2013 in “Clinical and Developmental Immunology” Alopecia areata is caused by immune system attacks on hair follicles, often triggered by viral infections.
