Abstract:
1. A method of remyelinating a demyelinized lesion due to injury in the brain or spinal cord of a patient, comprising obtaining bone marrow cells from the patient, diluting the bone marrow cells, centrifuging the bone marrow cells, thereby separating a mononuclear cell fraction having a specific gravity of 1.07 to 1.1 g/mL, collecting said mononuclear cell fraction, suspending said mononuclear cell fraction in a serum-free medium to form a suspension, centrifuging said suspension to yield a centrifuged mononuclear cell fraction and a supernatant, removing said supernatant from the centrifuged mononuclear cell fraction, resuspending said centrifuged mononuclear cell fraction in a serum-free medium, thereby forming a resulting mononuclear cell fraction, and injecting said resulting mononuclear cell fraction directly into the lesion in the patient, whereby the injected mononuclear cell fraction migrates to neural tissue in the patient, differentiates into neural cells, and forms myelinated axons in the demyelinated lesion three weeks after injection.
