摘要
During apoptosis, nuclear pores undergo strong modifications, which are described here in five different apoptotic models. Conventional electron microscopy, supported by freeze-fracture analysis, showed a constant migration of nuclear pores towards the diffuse chromatin areas. In contrast, dense chromatin areas appear pore-free and are frequently surrounded by strongly dilated cistemae. A possible functional significance of this pore behaviour during apoptosis is discussed.
