In vitro cultured shrimp cells can serve as useful and indispensable tool for the proliferation and characterization of shrimp viruses as well as production of effective diagnostic reagents and anti-virus vaccines. Despite numerous attempts, no continuous shrimp cell line has yet been established due to the absence of active mitosis and failure to be immortalized in the in vitro cultured shrimp cells. We have established an improved primary cell culture and subculture system as evidence of rapid initiation of cell migration (2-3 h after seeding) and formation of 70%~80% confluent cell monolayer (within 16~24 h), and efficient detachment (>90%) and reattachment (50%-60%) with digestion solutions of HyQTase and ECDS, respectively. Recently, an embryonic cell culture system has been developed from the limb bud embryos of penaeus shrimps (Marsupenaeus japonicas) which includes the effective disinfection and sterilization of shrimp embryos, rapid disaggregation of vialble embryonic cells and cell mass, and optimal shrimp medium. The dissociated embryonic cells attached within 3 hours after seeding and differentiated into fibroblast- and neuron-like cells. Some of the fibroblast-like cells behave like cardiac muscle cells with rythmic beating. The embryonic cell monolayer can survive over 23 days and be subcultured only once due to the absence of active mitosis. More works are needed to initiate the mitosis of the in vitro cultured shrimp cells.
