Cover: A cluster of motor neurons and neural fibers derived from human embryonic stem cells in the lab of University of Wisconsin-Madison stem cell researcher and neurodevelopmental biologist Su-Chan-Zhang. The motor neurons are shown in red, neural fibers appear green, and the blue specks indicate DNA in cell nuclei. These motor neurons were developed from one of James Thomson’s original human embryonic stem cell lines. Copyright for the photograph is held by the University of Wisconsin’s Board of Regents.
