  • GRID ETCHER
    Publication number: 20080069956
    Abstract: An apparatus and process for monitoring migratory cell proliferation with restricted migration on a substrate includes providing a substrate, coating the substrate with extracellular matrix, plating cells suspended in cell culture media on extracellular matrix, and placing intersecting channels across the extracellular matrix components by removing the extracellular matrix components from the channels to isolate islands of the extracellular matrix components on the substrate. When the cells are immersed with a fluid, migration of the cells is confined to the isolated islands of the extracellular matrix components, permitting long-term observation of a migratory population.
    Type: Application
    Filed: September 28, 2007
    Publication date: March 20, 2008
    Applicant: The Government of the U.S.A., as represented by the Secretary of Health and Human Services
    Inventors: Rea Ravin, James Sullivan, Daniel Hoeppner, David Munno, Ron McKay
