“The NIH Roadmap is intended to be an “incubator space” for programs that, due to their cross-cutting relevance and/or complexity, warrant concerted attention from NIH as a whole. Consistent with its “incubator” function, the Roadmap stimulates research or the development of research resources with the expectation that the programs will either be completed within a 5–10 year timeframe or will transition out of the “incubator space” as they become integral to Institutes and Center’s (IC) activities.”  For information on NIH’s roadmap initiatives see: http://nihroadmap.nih.gov/commonfundupdate.asp
