New Published Data Show Pluristem's PLX Cells Protect Neurons

HAIFA, Israel, Dec. 22, 2014 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading developer of placenta-based cell therapy products, announced today that a study of PLacental eXpanded (PLX) cells was accepted for publication in the February, 2015 issue of Biochimica et Biophysica Acta Molecular Cell Research. The study results show that PLX cells protect PC12 cells – an established model of various nerve cells including dopaminergic neurons – from death after oxygen and glucose deprivation. The protective effects of PLX cells were strongly correlated with the secretion of interleukin 6 (IL-6) and vascular endothelial growth factor (VEGF), which are known to have neuroprotective effects in humans with injuries to the nervous system that can occur after events such as a stroke.

"Our findings suggest that PLX cells may potentially treat damaged nerves, and may corroborate and explain the mechanism that leads to one of our findings in our Phase I trial in critical limb ischemia. In that study, patients treated with PLX cells had a statistically significant reduction in pain as compared to their baseline. An earlier preclinical study, published in the journal Brain Research, showed that PLX cells may effectively treat ischemic stroke," stated Pluristem CEO Zami Aberman.

Aberman continued, "These latest findings also call to mind two earlier preclinical studies, which indicated that PLX cells may be an effective treatment for both neuropathic and inflammatory nerve pain, suggesting that PLX cells could be a potential treatment for chronic nerve pain resulting from conditions such as diabetic neuropathy."

The study, titled "Human PLacental eXpanded (PLX) mesenchymal-like adherent stromal cells confer neuroprotection to nerve growth factor (NGF)-differentiated PC12 cells exposed to ischemia by secretion of IL-6 and VEGF", was conducted jointly by researchers at Pluristem and Prof. Philip Lazarovici, Jacob Gitlin Chair in Physiology and Pharmacology at the School of Pharmacy Institute for Drug Research at the Hebrew University and co-authored by Prof. Ephraim Yavin of the Department of Neurobiology at the Weizmann Institute of Science. The study was supported by the Magnet program of Israel's Ministry of Economy.

For example, forward-looking statements are used in this press release when we discuss the potential of PLX cells to treat damaged nerves and to treat ischemic stroke, and the potential of PLX cells to be an effective treatment for both neuropathic and inflammatory nerve pain. In addition, historic results of scientific research and clinical and preclinical trials do not guarantee that the conclusions of future research or trials would not suggest different conclusions or that historic results would not be interpreted differently in light of additional research and clinical and preclinical trials results. These forward-looking statements and their implications are based on the current expectations of the management of Pluristem only, and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements.
