In vitro Cultivation and Visualization of Malaria Liver Stages in Primary Simian Hepatocytes.

Human liver is the primary and obligatory site for malaria infection where sporozoites invade host hepatocytes. Malaria hepatic stages are asymptomatic and represent an attractive target for development of anti-malarial interventions and vaccines. However, owing to lack of robust and reproducible in vitro culture system, it is difficult to target and study this imperative malaria liver stage. Here, we describe a procedure that allow cultivation and visualization of malaria hepatic stages including dormant hypnozoites using primary simian hepatocytes. This method enables sensitive and quantitative assessment of different hepatic stages in vitro.
