Gametocytogenesis by Plasmodium falciparum is essential for transmission of the parasite from human to mosquito, yet developing gametocytes lack expression of surface proteins required for cytoadherence. Therefore, elimination from the circulation should occur unless they are sequestered in regions of low blood flow such as the extracellular spaces of the bone marrow. Our data indicate that gametocytogenesis is enhanced in the presence of erythroid progenitors found within the bone marrow. Furthermore, atomic force microscopy indicates that developing gametocytes undergo remarkable shifts in their erythrocyte membrane elasticity, which may allow them to be retained within the bone marrow until maturation.
