Exosomes derived from human induced pluripotent stem cell-derived neural progenitor cells protect neuronal function under ischemic conditions.

Compared with other stem cells, human induced pluripotent stem cells-derived neural progenitor cells (iPSC-NPCs) are more similar to cortical neurons in morphology and immunohistochemistry. Thus, they have greater potential for promoting the survival and growth of neurons and alleviating the proliferation of astrocytes. Transplantation of stem cell exosomes and stem cells themselves have both been shown to effectively repair nerve injury.
