ROCKVILLE, Md., Jan. 26 /PRNewswire-FirstCall/ -- Neuralstem, Inc.
(NYSE Alternext US: CUR) today announced that it 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. (Logo:

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." About the Technology The
newly patented method uses cMyc-ER, a recombinant fusion of two
proteins normally present in cells, c-Myc, a human cell-cycle
regulating protein, and estrogen receptor (ER), a human protein
that is activated by estrogen. By transiently increasing the
concentration of the c-Myc protein, a cell inserted with cMyc-ER is
able to overcome the natural aging process inherent in the cell
without losing any of its stem cell properties. The immortalized
human neural stem cell can be grown for over 60 cell-doublings and
is clonally expandable (that is starting from one cell). About
Neuralstem 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. Major Central
Nervous System diseases targeted by the Company with research
programs currently underway include: Ischemic Spastic Paraplegia,
Traumatic Spinal Cord Injury, Huntington's disease and Amyotrophic
Lateral Sclerosis (ALS). The Company filed an IND (Investigational
New Drug) application with the FDA for ALS clinical trials in
December, 2008, and has entered into a collaborative agreement with
Albert-Ludwigs-University, in Freiburg, Germany, to develop
clinical trials for Huntington's disease. In pre-clinical work, the
company's cells have extended the life of rats with ALS (Lou
Gehrig's disease) as reported the journal TRANSPLANTATION, in
collaboration with Johns Hopkins University researchers, and also
reversed paralysis in rats with Ischemic Spastic Paraplegia, as
reported in NEUROSCIENCE on June 29, 2007, in collaboration with
researchers at University of California San Diego. Cautionary
Statement Regarding Forward Looking Information This news release
may contain forward-looking statements made pursuant to the "safe
harbor" provisions of the Private Securities Litigation Reform Act

that involve risks and uncertainties, including, without
limitation, risks inherent in the development and commercialization
of potential products, uncertainty of clinical trial results or
regulatory approvals or clearances, need for future capital,
dependence upon collaborators and maintenance of our intellectual
property rights. Actual results may differ materially from the
results anticipated in these forward-looking statements. Additional
information on potential factors that could affect our results and
other risks and uncertainties are detailed from time to time in
