135 citations,
January 2014 in “Seminars in Cell & Developmental Biology” Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.
133 citations,
September 2013 in “Nature Reviews Molecular Cell Biology” Different types of stem cells and their environments are key to skin repair and maintenance.
132 citations,
February 2013 in “Biochimica et Biophysica Acta (BBA) - General Subjects” TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.
132 citations,
October 1995 in “Journal of the American Academy of Dermatology” Electrolysis is effective for permanent hair removal, but technique is key to avoid scarring, and sometimes hormonal treatment is needed for women with hirsutism.
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.
127 citations,
January 2015 in “Journal of Biological Rhythms” The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
127 citations,
January 2013 in “PLOS ONE” Probiotic bacteria improved skin and hair health in aged mice.
124 citations,
February 2018 in “Nature Reviews Genetics” Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
124 citations,
July 2012 in “Archives of Dermatological Research” Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.
122 citations,
July 2005 in “The FASEB journal” Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.
120 citations,
November 2014 in “Biological Reviews” The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
118 citations,
January 2016 in “Current Topics in Developmental Biology” The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.
118 citations,
September 2004 in “Clinics in Dermatology” Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.
112 citations,
July 1998 in “Journal of Investigative Dermatology” Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.
111 citations,
March 2012 in “Expert Opinion on Drug Delivery” Liposomes could improve how skin care products work but are costly and not very stable.
109 citations,
