August 2012 in “Biochimica et Biophysica Acta (BBA) - General Subjects” TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.
131 citations,
March 2004 in “The American journal of pathology” Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.
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,
December 2005 in “Experimental Dermatology” Stress can stop hair growth in mice, and treatments can reverse this effect.
124 citations,
October 2019 in “Frontiers in Immunology” Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.
124 citations,
February 2018 in “Nature Reviews Genetics” Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
122 citations,
April 1995 in “Journal of Cutaneous Pathology” The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.
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.
119 citations,
July 2016 in “Annals of the New York Academy of Sciences” Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.
118 citations,
April 1998 in “Dermatologic Clinics” Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.
