| Outline of Final Research Achievements |
Human iPSCs were induced to differentiate into cortical neuron progenitors and were transplanted intracranially into ipsilesional cortex 7 days post MCAO (90 minutes) or normal rats and also compared with sham transplanted rats. Transplantation in MCAO lesion brain increased graft reactivity, as demonstrated by higher degree of axonal outgrowth, cellular migration and directional preference toward ischemic border. Endogenous recovery was enhanced by transplantation at limited time point (± 2 weeks post transplantation), particularly forelimb movement after stimulation of impaired side. The improvement of functional recovery might be attributed to the declining of microglia infiltration. Human iPSCs-derived cortical neuron progenitors able to survive, migrate, and differentiate in ischemic environment and might contribute to behaviour recovery.
