Frederick P. Prince, chair of the Department of Biological Sciences and professor of anatomy, authored a chapter on human Leydig cells in The Leydig Cell in Health and Disease, published by Humana Press in June. The book provides a comprehensive study of the cell, which is found in the testicles and secretes testosterone, while exploring a wide variety of current and potential clinical applications. Prince’s chapter is titled “The Human Leydig Cell: Functional Morphology and Developmental History.” Prince also created the color image of Leydig cells featured on the book’s cover.
