Accelerated Induction of Cortical Neurons from hiPSCs
In Brief
Qi et al. describe an approach for the accelerated induction of early-born cortical neurons from human induced pluripotent stem cells. At day 8 of differentiation the resulting neurons were transplanted into postnatal mouse cortex and established long distance connections. In addition, cells remaining in culture exhibit functional electrophysiological properties by day 16.
hiPSCs were plated one day prior to differentiation in conditioned medium. KSR medium was used to start differentiation the next day and was gradually replaced with N2B7 medium from day 4, reaching 100% at day 8.
