StemCells, Inc. Announces New Preclinical Data Showing HuCNS-SC(R) Cells Preserve Visual Function by Keeping Photoreceptors Normal and Healthy NEWARK, Calif., Sept. 18, 2013 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM) today announced the publication of preclinical data confirming that the Company's proprietary HuCNS-SC cells (purified human neural stem cells) preserve photoreceptor cells and visual function in a widely used model of retinal degeneration. The data show not only that HuCNS-SC cells preserve the number of photoreceptors that would otherwise be lost, but also that the surviving photoreceptors appear healthy and normal, and maintain their synaptic connection to other important cells necessary for visual function. The study was published in Investigative Ophthalmology and Visual Science (IVOS), the journal of the Association for Research in Vision and Ophthalmology, and is available at (http://www.iovs.org/content/early/recent.) These results are highly relevant to disorders of vision loss, the most notable of which is age-related macular degeneration (AMD), which afflicts approximately 30 million people worldwide. "This study demonstrates that, at the cellular and sub-cellular level, the surviving photoreceptors have all the components that characterize a healthy and normal photoreceptor, and they have the correct synaptic connections," said Nicolas Cuenca, PhD, Professor in the Department of Physiology, Genetics and Microbiology at the University of Alicante, Spain, and lead author of the paper."The robust anatomical preservation of the photoreceptors and their synaptic connections most likely underlie the preservation of visual function. "In addition, this study confirmed our preliminary hypothesis that HuCNS-SC cells phagocytose photoreceptor outer segments. The phagocytic activity of the HuCNS-SC cells restores a function normally performed by retinal pigmented epithelial (RPE) cells." The Company is currently conducting a Phase I/II clinical trial in the dry form of AMD, the most prevalent form of the disease. The preclinical data underlying this Phase I/II clinical trial was previously published in the European Journal of Neuroscience (http://onlinelibrary.wiley.com/doi/10.1111/j.1460-9568.2011.07970.x/abstract).That data demonstrated that HuCNS-SC cells protect host photoreceptors (both rods and cones) and preserve vision in the Royal College of Surgeons (RCS) rat, a well-established animal model of retinal disease that has been used extensively to evaluate potential cellular therapies. The Company's Phase I/II clinical trial in dry AMD is currently enrolling patients at the Byers Eye Institute at Stanford in Palo Alto, California, and at the Retina Foundation of the Southwest in Dallas, Texas.The Company recently dosed the first high-dose patient in the trial.To date, a total of five patients have been dosed in the 16-patient trial.Patients interested in participating in the clinical trial should contact the Byers Eye Institute at Stanford at (650) 498-4486 or the Retina Foundation of the Southwest at (214) 363-3911. The Company is working to open additional sites in the United States. About StemCells, Inc. StemCells, Inc. is engaged in the research, development, and commercialization of cell-based therapeutics and tools for use in stem cell-based research and drug discovery. The Company's lead therapeutic product candidate, HuCNS-SC® cells (purified human neural stem cells), is currently in development as a potential treatment for a broad range of central nervous system disorders. In a PhaseI clinical trial in Pelizaeus-Merzbacher disease (PMD), a fatal myelination disorder in children, the Company has shown preliminary evidence of progressive and durable donor-derived myelination in all four patients transplanted with HuCNS-SC cells. The Company is conducting a Phase I/II clinical trial in chronic spinal cord injury in Switzerland and Canada and has reported positive interim data for the first three patients. The Company is also conducting a Phase I/II clinical trial in dry age-related macular degeneration (AMD) at two sites in the United States. In addition, the Company is pursuing preclinical studies in Alzheimer's disease, with support from the California Institute for Regenerative Medicine (CIRM). StemCells also markets stem cell research products, including media and reagents, under the SC Proven® brand.Further information about StemCells is available at http://www.stemcellsinc.com.
