Valerie Horsley Gets Under Skin in The Scientist
In 2009, Horsley set up her own lab at Yale University. Among several lines of inquiry, including characterizing the stages of keratinocyte specification and understanding adhesions between these epidermal cells, she’s been collaborating with her husband, Yale’s Matthew Rodeheffer, on the role of adipocytes in hair growth. They found that in the skin, adipogenesis occurs in parallel with the growth of hair, and regresses when hair follicles die.3 Although she wasn’t sure at first whether she wanted to collaborate with her husband, the partnership yielded an entirely new appreciation for fat cells in hair growth. “No one had looked at it before,” says Horsley. “It’s pretty much what my lab has been working on since.”
