252 citations,
July 2009 in “Seminars in Cell & Developmental Biology” The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.
155 citations,
May 2016 in “Nature communications” Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.
134 citations,
August 2020 in “Experimental dermatology” Hair follicles are normally protected from the immune system, but when this protection fails, it can cause hair loss in alopecia areata.
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.
60 citations,

59 citations,
March 2020 in “Journal of Biomedical Science” Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.
55 citations,
December 2019 in “The journal of allergy and clinical immunology/Journal of allergy and clinical immunology/The journal of allergy and clinical immunology” The review suggests that other immune cells besides CD8+ T cells may contribute to alopecia areata and that targeting regulatory cell defects could improve treatment.
42 citations,
October 2016 in “Annual Review of Cell and Developmental Biology” Fat cells are important for tissue repair and stem cell support in various body parts.
