Infо fоr Questiоns 17-20 The following is from а brief description of some reseаrch on hаir growth: “New drugs promoting hair growth may soon be on the market, as researchers from UCLA have developed a new way to activate the stem cells in the hair follicle to make hair grow. Hair follicle stem cells are long-lived cells in the hair follicle that are present in the skin and produce hair throughout a person’s lifetime. The stem cells are normally inactive, but can quickly activate during a new hair cycle when growth occurs.” Continuing, “….researchers from the University of Utah increased lactate production genetically in the mice to accelerate hair follicle stem cell activation and ultimately increase the hair cycle. Before this, no one knew that increasing or decreasing the lactate would have an effect on hair follicle stem cells,” William Lowry, a professor of molecular, cell, and developmental biology at UCLA, said in a statement. “Once we saw how altering lactate production in the mice influenced hair growth, it led us to look for potential drugs that could be applied to the skin and have the same effect.
