Summary of "ToolBox: Live-Imaging of intracellular organelle transport in iPSC-derived neurons."

Induced pluripotent stem cells (iPSCs) hold promise to revolutionize studies of intracellular transport in live human neurons and to shed new light on the role of dysfunctional transport in neurodegenerative disorders. Here, we describe an approach for live-imaging axonal and dendritic transport in iPSC-derived cortical neurons. We use transfection and transient expression of genetically-encoded fluorescent markers to characterize the motility of Rab-positive vesicles, including early, late and recycling endosomes, as well as autophagosomes and mitochondria in iPSC-derived neurons. Comparing transport parameters of these organelles with data from primary rat hippocampal neurons, we uncover remarkable similarities. In addition, we generated LAMP1-EGFP knock-in iPSCs and show that knock-in neurons can be used to study transport of endogenously labeled vesicles, as a parallel approach to the transient overexpression of fluorescently-labeled organelle markers.

Medical and Biotech [MESH] Definitions

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

Membrane-limited structures derived from the plasma membrane or various intracellular membranes which function in storage, transport or metabolism.

A broad category of proteins involved in the formation, transport and dissolution of TRANSPORT VESICLES. They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.

Disorders characterized by defective transport of amino acids across cell membranes. These include deficits in transport across brush-border epithelial cell membranes of the small intestine (MICROVILLI) and KIDNEY TUBULES; transport across the basolateral membrane; and transport across the membranes of intracellular organelles. (From Nippon Rinsho 1992 Jul;50(7):1587-92)

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.
