- We developed the new methods to observe the migratory behavior of the human cortical neuron derived from induced pluripotent stem cells in vitro.
- Cortical neurons derived from induced pluripotent stem cells showed two-stroke like movement.
- We successfully generated migrating cortical neurons from lissencephaly-patient derived induced pluripotent stem cells.
BackgroundNeuronal migration is considered a key process in human brain development. However, direct observation of migrating human cortical neurons in the fetal brain is accompanied by ethical concerns and is a major obstacle in investigating human cortical neuronal migration.New methodWe established a novel system that enables direct visualization of migrating cortical neurons generated from human induced pluripotent stem cells (hiPSCs).ResultsWe observed the migration of cortical neurons generated from hiPSCs derived from a control and from a patient with lissencephaly.MethodsOur system needs no viable brain tissue, which is usually used in slice culture. Migratory behavior of human cortical neuron can be observed more easily and more vividly by its fluorescence and glial scaffold than that by earlier methods.ConclusionsOur in vitro experimental system provides a new platform for investigating development of the human central nervous system and brain malformation.
