In vitro sexual dimorphism establishment in schistosomes.

In vitro culture with human serum enables long-term development and clear sexual dimorphism in Schistosoma parasites, unlike traditional FBS-based methods.

• Why it matters: Understanding the cellular and molecular basis of schistosome sexual differentiation is limited by challenges in studying parasite development in vivo, hindering disease control efforts.
• What they did: A refined protocol was developed for culturing newly transformed cercariae with human serum, promoting sustained growth, sexual dimorphism, and cell proliferation over time.
• The result: This method allows reproducible in vitro parasite development, opening new avenues for studying sexual biology and testing interventions across the parasite's life cycle.
