Pluristem to Present at the International Congress of Radiation Research and Chair Two Panels at the Annual Meeting of the International Society for Cellular Therapy

HAIFA, ISRAEL, May 27, 2015 -- Pluristem Therapeutics Inc. (NasdaqCM: PSTI) TASE: PLTR), a leading developer of placenta-based cell therapy products, today announced participation at two important conferences:

International Congress of Radiation Research Location: Kyoto, Japan Date: May 27, 2015

Presentation title: The Mechanism of Action of Placenta Derived Cellular Therapy in Mitigation of Acute Radiation Syndrome

Presented by: Racheli Ofir, Ph.D., Vice President of Research & Intellectual Property

The Japanese government is focused on the development of treatments for Acute Radiation Syndrome (ARS), as is the U.S. National Institutes of Health. ARS is caused by exposure to high levels of radiation, and produces severe, sometimes lethal damage to the bone marrow and other physiologic systems and organs. Pluristem recently announced the results of an NIH study conducted in animals exposed to high levels of radiation: injection of PLX-R18 cells, as compared to injection of a placebo, resulted in a significant improvement in survival, as well as in the recovery of blood cell production after irradiation. These blood cells are necessary to resist infection, prevent hemorrhage, and transport oxygen throughout the body.
