Abstract
The ability to generate spinal cord motor neurons from human pluripotent stem cells (hPSCs) is of great use for modelling motor neuron–based diseases and cell-replacement therapies. A key step in the design of hPSC differentiation strategies aiming to produce motor neurons involves induction of the appropriate anteroposterior (A-P) axial identity, an important factor influencing motor neuron subtype specification, functionality, and disease vulnerability. Most current protocols for induction of motor neurons from hPSCs produce predominantly cells of a mixed hindbrain/cervical axial identity marked by expression of Hox paralogous group (PG) members 1-5, but are inefficient in generating high numbers of more posterior thoracic/lumbosacral Hox PG(8-13)+ spinal cord motor neurons. Here, we describe a protocol for efficient generation of thoracic spinal cord cells and motor neurons from hPSCs. This step-wise protocol relies on the initial generation of a neuromesodermal-potent axial progenitor population, which is differentiated first to produce posterior ventral spinal cord progenitors and subsequently to produce posterior motor neurons exhibiting a predominantly thoracic axial identity.
