Abstract
Parenchymal cells are cultivated on cultivated endothelial cells or cultivated fibroblasts which have been separated by a surface of a specific hydrophilic polymer, and which have been patterned. A culture which contains thus formed patterned spheroids of cultivated parenchymal cells is thereby provided by this invention. This culture maintains a function which is specific to the parenchymal cells over a long period of time.
