Plasmodium falciparum sexual stage gametocytes undergo remarkable transformations as they develop to maturity inside the red blood cell of their host. This dramatic metamorphosis is highlighted in these 3D rendered images from Serial Block Face Scanning Electron Microscopy (SBF-SEM). The formation of a membrane structure called the inner membrane complex (magenta) which drives the gametocyte elongation process. The nucleus (yellow), mitochondria (red) and red blood cell (dark red) are also rendered. Dixon et al.
