Publication number: 20200332254Abstract: This invention provides populations of neural cells bearing markers of glial cells, such as oligodendrocytes and their precursors. The populations are generated by differentiating pluripotent stem cells such as human embryonic stem cells under conditions that promote enrichment of cells with the desired phenotype or functional capability. Various combinations of differentiation factors and mitogens can be used to produce cell populations bearing markers of oligodendrocyte precursor cells. Upon further differentiation form complex processes characteristic of mature oligodendrocytes. The cells are capable of forming myelin sheaths, and can be used therapeutically improve function of the central nervous system.Type: ApplicationFiled: February 24, 2020Publication date: October 22, 2020Inventors: Hans S. Keirstead, Gabriel I. Nistor

Patent number: 6969516Abstract: A method is described comprising the combined administration of a novel composition comprising serum complement proteins with complement-fixing antibodies to induce transient disruption of myelin and/or demyelination. The antibodies specifically bind to one or more epitopes of myelin, and complement proteins. A method is also described for promoting regrowth, repair, and regeneration of neurons in a mammalian subject. The methods can be used following immediate or chronic injury.Type: GrantFiled: October 28, 1998Date of Patent: November 29, 2005Assignee: MBM & Co.Inventors: John D. Steeves, Jason K. Dyer, Hans S.
