,
July 2003 in “European journal of biochemistry” This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.
91 citations
,
May 2003 in “American Journal of Pathology” This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.
28 citations
,
January 2003 in “Skin pharmacology and physiology” This study found that melatonin's effect on HaCaT keratinocyte proliferation varied with concentration and incubation time, with no cytotoxic effects observed at suitable concentrations for skin treatment.
