Scientists at the University of Wisconsin-Madison have spent years trying to unravel the details of Down syndrome: What happens inside the womb, how the genetic disorder alters the formation of neurons, and what specific processes affect brain development. The work can’t proceed without studying fetal tissue. Anita Bhattacharyya, an associate professor of cell and regenerative biology, said her lab’s findings so far are significant, having identified a layer of late-developing neurons that are reduced in the brains of fetuses with Down syndrome. If she were to start her career again, however, she isn’t sure she would follow the same path. “It seems too risky,” she said.
