title: 4Pi-microscopy of the Golgi apparatus in live mammalian cells.
abstract: We report the applicability of 4Pi-microscopy to live mammalian cells. Controlled interference of the counterpropagating wavefronts is possible despite the slight variations in cellular refractive index. Superresolved 3D-fluorescence imaging is exemplified with the first representation of the Golgi apparatus in a live cell at approximately 100 nm resolution.
