Summary: | Microcarrier beads were evaluated as substrates for the propagation of five anchorage-dependent fish cell lines. Growth of rainbow trout gonad (RTG-2) and Atlantic salmon cells was limited on microcarriers maintained in suspension. However, stationary microcarriers were suitable substrates for the growth of RTG-2, AS, Chinook salmon embryo (CHSE-214), and fathead minnow cells. Cell yields ranged from 2 × 10 6 to 2.9 × 10 6 cells per ml, representing 7- to 10-fold increases over the initial cell concentrations. The yield of new RTG-2 cells per unit volume of growth medium was 2.8 times greater in microcarrier cultures than in standard monolayer cultures. Northern pike cells failed to grow on microcarriers. Yields of infectious pancreatic necrosis virus propagated in microcarrier cultures of RTG-2 cells were more than twice the yields in standard monolayer cultures. The greater economy of microcarrier cultures in terms of growth vessel and medium requirements holds great promise for the large-scale production of anchorage-dependent fish cell cultures and fish viruses. |
