September 2005 in “Proceedings of the National Academy of Sciences of the United States of America” The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

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,

109 citations,
July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology” Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
97 citations,

October 2006 in “Current opinion in cell biology” Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.
85 citations,
July 2002 in “Pigment Cell Research” The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.
82 citations,

March 2016 in “Cell” The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.
82 citations,
August 2006 in “Pharmacology, Biochemistry and Behavior” Certain steroids in the brain affect mood and symptoms of depression, and treatments targeting these steroids show promise for improving these symptoms.
81 citations,
September 2005 in “The American journal of pathology” Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.
