In October 2008, the new John G. Rangos Sr. Research Center, located on the Children's Hospital of Pittsburgh's new 10-acre hospital campus in Lawrenceville, opened its doors to one of the fastest growing pediatric research programs in the country. This center is the hub for pediatric research performed in Pittsburgh. The home for Children’s research is designed around the concept of the open laboratory. The flexible central lab space encourages interaction and the sharing of equipment. The space accommodates 70 principal investigators and supports biomedical research, including genomics, cellular imaging, signal transduction, structural biology, immunology and neuro-science, among other fields.
