,
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
,
May 2017 in “InTech eBooks” Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
March 2024 in “Journal of Microbiology and Biotechnology” Phloroglucinol may help improve hair loss by promoting hair growth and reducing oxidative stress.
June 2020 in “The journal of investigative dermatology/Journal of investigative dermatology” The enzymes Tet1, Tet2, and Tet3 are important for the development of hair follicles and determining hair shape by controlling hair keratin genes.
28 citations
,
October 2019 in “Seminars in Cell & Developmental Biology” Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.
18 citations
,

17 citations
,
June 2017 in “British Journal of Dermatology” The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.
