News From the Field
Self-assembled Materials Form Mini Stem Cell Lab

March 27, 2008

sac Northwestern University researchers have discovered a new and unexpected mode of self-assembly involving a polymer (hyaluronic acid) and a small molecule (peptide amphiphiles). When brought together, the two instantly assemble into a flexible but strong sac in which the researchers can grow human stem cells, creating a sort of miniature laboratory. The sacs can survive for weeks in culture, and their membranes are permeable to proteins. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
