"In multicell organisms like humans, one fertilized egg can develop into all cell types with diverse biological functions that make up the body,” says Wang, an assistant professor in the Department of Animal Science within the College of Agriculture and Natural Resources. “Some of these cells become eggs (in female) and sperm (in male). This fascinating process forms a cycle of life and inspires me to understand how this happens."
