Neuralstem, Inc has received Official Notice of Allowance for its patent application, number 10/047,352, for Stable Neural Stem Cell Lines from the US Patent and Trade Office (USPTO). This patent covers the technology to immortalize any human neural stem cell, rendering its growth robust and long-lasting.
"We are pleased to have received the Notice of Allowance on this important technology," said president & CEO Richard Garr. "The technology behind this patent allows us to grow practically unlimited quantities of neural stem cells from all regions of the brain without regard to the natural mitotic (growth) limits of cells from a particular region.
Equally important, this technology is a next-generation immortalization process that avoids the harmful effects of traditional immortalization methods, which have invariably resulted in uncontrolled growth. Our technology provides the necessary assurance that the cell lines are fully controlled and remain consistent trial-over-trial and year-after-year.
This consistency is ultimately key to the commercialization of any cell products and greatly enhances our ability to deliver cell therapies for very prevalent diseases, such as stroke and traumatic brain injury. It will also enable, for the first time, systematic drug screening against many different kinds of normal human brain cells for new Central Nervous System (CNS) drugs, and stem cell-mediated protein delivery for neurologic diseases."
Neuralstem's patented technology enables, for the first time, the ability to produce neural stem cells of the human brain and spinal cord in commercial quantities, and the ability to control the differentiation of these cells into mature, physiologically relevant human neurons and glia.
