A system and method for enabling use of detailed consumer profiles for the purposes of targeted information delivery while protecting these profiles from disclosure to information providers or hostile third parties are disclosed herein. In one aspect of the invention, adult mammalian enteric neuronal progenitor cells can be induced to differentiate on various substrates derived from components or combinations of neural ECM compositions. Address information is generated that allows identification of the first CU within the picture by defining the position of the first CU and the size of the largest possible CU that can occupy this position within the picture.
