[Culture of epithelial cell lines in chemically defined media on microcarriers in biogenerators].
A rat liver epithelial cell line has been propagated on microcarriers in 11 or 21 laboratory culture vessels for cell culture in suspension on microcarriers (biogenerators) with Ham F10 or DME as basal synthetic culture medium either serum-supplemented (SSM), or serum-free (SFM), or serum- and protein-free (SPFM). Without serum, the use of DME allows a cellular growth in the biogenerator at least equivalent to that obtained in culture dishes. For the cultivation on microcarriers in SFM in a biogenerator the use during the first day of culture of spent serum-free medium previously incubated (SFMI) in confluent culture dishes avoids the substratum treatment with serum. Results concerning the Vero cell line cultured in SPFM are shown.
