Riassunto (Italiano)
This thesis aims to model the human corticospinal tract (CST) using cortical organoids (hCOs) and spinal cord organoids (hSpOs) derived from human iPSCs. Two complementary strategies were employed: (1) contact-based fusion of hCOs and hSpOs to form cortico-spinal assembloids, and (2) connectoid-based modeling using microfluidic chips to study long-range axonal connectivity. The spinal organoids were developed using an accelerated protocol and validated by the expression of motor neuron markers, while cortical organoids were assessed for layer-specific neuronal identity. Connectivity was evaluated across different microdevice platforms, including a custom 3D-printed chip (MED160), agarose-based systems, and PDMS microfluidic devices. Together, these models provide an in vitro platform to investigate CST development, axonal guidance, and applications in regeneration and disease modeling.
