Pluristem to Present at the Annual Meeting of the American Society of Hematology PLX-BMT Promotes the Engraftment of Human Umbilical Cord Blood Cells in Animals

NEW YORK--(BUSINESS WIRE)--

Pluristem Therapeutics, Inc. (OTCBB:PSTI), a leading bio-therapeutics company dedicated to the commercialization of non-personalized (allogeneic) cell therapy products for a variety of malignant, ischemic and autoimmune disorders, announced today that it has been chosen to present at the Annual Meeting of the American Society of Hematology (ASH) on December 8, 2007 in Atlanta, Georgia. Hematology experts from around the world will gather to discuss the latest developments in their field.

Dr. Moran Meiron, Research Director of Pluristem, will present pre-clinical results that demonstrate the potential of human placental-derived mesenchymal stromal cells (MSCs), grown in a 3D culture and termed PLacental eXpanded (PLX-BMT) cells, to promote the engraftment of CD34+ human umbilical cord blood (hUCB) cells in patients afflicted with leukemia and other hematological malignancies. The study suggests that co-transplantation of PLX-BMT may improve engraftment when using hUCB as the source of hematopoietic stem cells (HSCs).

Zami Aberman, Pluristem's President & CEO states, "Our ability to improve the engraftment of hUCB in the treatment of severe blood disorders, as will be presented by Dr. Meiron at the ASH conference in Atlanta, has attracted the attention of the hematology community. We are honored to have been chosen to present at this meeting of prestigious hematology experts. Our revolutionary 3D expansion process could lead to a wider use of hUCB cells in treating various types of blood cancer and potentially benefiting up to 100,000 patients annually."

About Pluristem

Pluristem Therapeutics, Inc. is a Company dedicated to the commercialization of non-personalized (allogeneic) stem cell therapy products for the treatment of numerous severe degenerative, malignant and autoimmune disorders. The Company's first product, PLX-BMT, is directed at resolving the global shortfall of matched tissue for bone marrow transplantation (BMT) by improving the engraftment of hematopoietic stem cells (HSCs) contained in umbilical cord blood (UCB).

Pluristem's products are derived from mesenchymal stromal cells (MSCs) obtained from the placenta and not from embryonic stem cells. They are expanded in the Company's proprietary PluriX(TM) 3D bioreactor that imitates the natural microstructure of bone marrow and does not require supplemental growth factors, cytokines or other exogenous materials. Pluristem believes the resultant expanded cells, termed PLX cells, are multi-potent and able to differentiate into a variety of cell types. Recent evidence also suggests their efficacy may be related to their secretion of cytokines or other potent immune modulators. Furthermore, PLX cells are believed to be immune-privileged, hence protecting the recipient from immunological reactions that often accompany transplantation.

Pluristem has offices in the USA with research and manufacturing facilities in Israel.
