Protocol for generating human induced neural progenitor cells from immobilized adult peripheral blood

Summary: Generating induced neural stem/progenitor cells (iNPCs) from somatic cells for medical applications has remained challenging. Here, we describe a reliable protocol to make human iNPCs from a small volume of immobilized adult peripheral blood by direct reprogramming. We have verified that the integration-free human iNPCs can efficiently differentiate into mature neurons in mouse brain upon transplantation and display capacities to functionally replace the damaged neurons, suggesting their potential as donor cells in developing replacement medicine for neurodegenerative diseases.For complete details on the use and execution of this protocol, please refer to Zhang et al. (2019).
