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.
124 citations,

106 citations,
July 2013 in “Advances in wound care” UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.
60 citations,
September 2015 in “Expert Review of Clinical Immunology” Lymphocytes, especially CD8+ T cells, play a key role in causing alopecia areata, and targeting them may lead to new treatments.
54 citations,
August 2019 in “Bioscience trends” Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.
53 citations,
August 2019 in “American journal of human genetics” FOXN1 gene variants cause low T cells and immune issues from birth.
49 citations,
September 2007 in “Journal of Investigative Dermatology” The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

January 2013 in “Frontiers in genetics” Stem cells can help other stem cells by producing supportive factors.
30 citations,
December 2018 in “Trends in Endocrinology and Metabolism” Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

March 2018 in “Experimental Dermatology” The guide explains how to study human skin fat cells and their tissue, aiming to improve research and medical treatments.
19 citations,
March 2003 in “Journal of Investigative Dermatology” Mechlorethamine treatment regrew hair in mice by killing immune cells causing hair loss without harming hair follicles.
18 citations,
