A method of producing oligodendrocytes recapitulates the major steps of
oligodendrocyte differentiation in a significantly shorter time than the 75-95 days required for the previous protocol. The
cannabinoid receptor agonist, WIN55212-2, induces NSC differentiation and promotes OLIG2+OPC induction. WIN-derived OLIG2+
progenitor cells differentiate into PDGFR α+ OPCs, which are highly migratory, can further differentiate into mature OLs with strong myelination ability. When WIN-derived OPCs were transplanted to the
lesion site, the
motor ability of
spinal cord injury (SCI) mice was significantly improved from the second week after
transplantation.
Immunostaining results showed that WIN-derived OPCs could differentiate into mature OLs and myelinate injured axons. The method and product have wide applications in the field of cellular therapy, especially for
spinal cord injury with remarkable therapeutic effects.
