| Research Abstract |
Human choriocarcinoma cells have been used as models for studying transcellular drug transport through placental trophoblasts. However, these models allow the transport of low-molecular-weight drugs through intercellular gap junctions. This study aimed to investigate the differentiation patterns of JEG-3 choriocarcinoma cells under different culture conditions and establish the appropriate model of in vitro syncytiotrophoblast drug transport. The differentiation pattern of JEG-3 cultured in CS-C resembled the syncytiotrophoblast-like differentiation signal characterizations in vivo. In conclusion, the syncytiotrophoblast-like models of differentiating JEG-3 cells cultured in CS-C might be appropriate for evaluating drug transport across the placental trophoblast.
