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.

1 citations,
April 2023 in “Frontiers in Immunology” New treatments for hair loss from alopecia areata may include targeting immune cells, using stem cells, balancing gut bacteria, applying fatty acids, and using JAK inhibitors.
1 citations,
January 2017 in “Springer eBooks” Understanding the immune-related causes of Alopecia Areata has led to potential treatments like JAK inhibitors.
December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” Aged individuals heal wounds less effectively due to specific immune cell issues.
April 2021 in “Sohag Medical Journal” Alopecia areata is an autoimmune condition causing hair loss, linked to genetic factors and immune system issues, with no cure yet.

57 citations,
March 2019 in “Immunity” The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.
38 citations,
February 2021 in “Journal of Investigative Dermatology” Aging slows wound healing due to weaker cells and immune response.
22 citations,
August 2021 in “Frontiers in medicine” Immune cells in Hidradenitis suppurativa become more inflammatory and may be important for treatment targets.
15 citations,
July 1999 in “Dermatologic Clinics” The document concludes that immune system abnormalities cause alopecia areata, but the exact process is still not completely understood.
2 citations,
August 2022 in “Emergency medicine international” Keloid skin disorder involves abnormal fibroblast activation and immune response, linked to a group of genes including FGF11.
1 citations,
June 2023 in “Reproduction” Microglia, the brain's immune cells, may contribute to Polycystic Ovary Syndrome (PCOS) by altering the female brain's structure and function, with kisspeptin neurons and GABA neurotransmitters also playing a role.
July 2023 in “Stem Cells Translational Medicine” Mesenchymal Stem/Stromal Cells (MSCs) help in wound healing and tissue regeneration, but can also contribute to tumor growth. They show promise in treating chronic wounds and certain burns, but their full healing mechanisms and potential challenges need further exploration.
