This study was designed to establish an in vitro primary culture of germinal cells of Echinococcus multilocularis, a parasite that causes alveolar echinococcosis of the liver (AEL). We also investigated the temperature-dependency of the cultured cells. The germinal cells, which originated from a human lesion, were cultured by an original fluid-suspension method at 25 degrees C or 37 degrees C for 4 weeks. Anchorage-dependent and -independent cells were observed by light microscopy, transmission electron microscopy, and immunocytochemistry to confirm their origin. Cell number and viability were examined by immunocytochemistry and mitochondrial exclusion test. The cultured cells were also inoculated into jirds (Meriones unguiculatus) to evaluate metacestode formation. Morphology and immunocytochemistry showed that the cultured cells were typically germinal cells. The cell number declined gradually over the 4-week culture period, but viability remained at 50% at 3 weeks. These findings were not associated with either of the two culture temperatures; moreover, host-associated cells were not noted in the cultured cells at 25 degrees C. The implanted cells formed metacestodes in the jird peritoneal cavity, and their histology demonstrated mature and typical alveolar-type echinococcal cysts. We successfully established an in vitro primary culture of germinal cells. This should contribute to future studies, and, hence, a better outcome for patients with AEL.
