Growth of

P falciparum in AA and CC cells. Parasite lines were cultured for 4 days (2 cycles) in either AA (▪) or CC (■) cells. Initial parasitemias were 0.1%. Parasite densities were counted after 3 and 4 days of culture. Mean parasitemias (± SD) achieved by this set of 5 parasite lines after 4 days of culture in either AA or CC cells are compared in the bar graph and are representative of 10 separate culture experiments.
