April 2015 in “Nature Reviews Molecular Cell Biology” Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.
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.
125 citations,

124 citations,
June 2020 in “Cell Stem Cell” Fat cells in the skin help start healing and form important repair cells after injury.
124 citations,
February 2018 in “Nature Reviews Genetics” Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
106 citations,

92 citations,
August 2017 in “Proceedings of the National Academy of Sciences of the United States of America” Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.
78 citations,
December 2020 in “Experimental Dermatology” Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

56 citations,
May 2017 in “Nature Cell Biology” Hair can regrow after certain stem cells are lost because other stem cells can take over their role.
53 citations,
April 2021 in “Cell Host & Microbe” Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.
51 citations,
September 2020 in “Cell Metabolism” Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.
51 citations,
