Human iPSC-derived neural stem cells engraft and improve pathophysiology of MPS I mice.

ABSTRACT: Mucopolysaccharidosis type I (MPS I) is a metabolic disorder characterized by a deficiency in α-l-iduronidase (IDUA), leading to impaired glycosaminoglycan degradation. Current approved treatments seek to restore IDUA levels via enzyme replacement therapy (ERT) and/or hematopoietic stem cell transplantation (HSCT). The effectiveness of these treatment strategies in preventing neurodegeneration is limited due to the inability of ERT to penetrate the blood-brain barrier (BBB) and HSCT's limited CNS reconstitution of IDUA levels. We reprogrammed human cord blood cells into induced pluripotent stem cells (iPSCs), differentiated them into human induced neural stem cells (hiNSCs), and sorted them using fluorescence-activated cell sorting (FACS). Our in vitro studies showed that these hiNS
