Impaired mitochondrial transport and morphology are involved in various neurodegenerative diseases. The presented protocol uses induced pluripotent stem cell-derived forebrain neurons to assess mitochondrial transport and morphology in hereditary spastic paraplegia. This protocol allows characterization of mitochondrial trafficking along axons and analysis of their morphology, which will facilitate the study of neurodegenerative disease.

The methodology assists in the analysis of variation in DNA replication dynamics in the presence of nanoparticles. Different methodologies can be adopted based on the cytotoxicity level of the material of interest. In addition, a description of the image analysis is provided to help in DNA fiber analysis.
