Abstract
PC12 cells on plastic grow as a single-layered lawn of cells which synthesize, store and secrete dopamine. In contrast, PC12 cells cultured on Englebreth-Holm-Swarm (EHS) tumor-derived extracellular matrix grow into multicellular aggregates. Matrix dissolution and cell migration appear to follow aggregate formation. PC12 cell plating efficiency is decreased on EHS-matrix but the doubling time of cells on EHS-matrix is comparable to plastic. Dopamine secretion and cellular content determined with a radioenzymatic assay as well as dopamine synthesis determined with cation-exchange chromatography are similar on a per cell basis in cultures of PC12 cells on plastic and EHS-matrix.
