Pluristem to Present at Annual Meeting of American Society of Hematology: Breakthrough Method Improves Engraftment of Umbilical Cord Blood in Treating Severe Blood Disorders.

NEW YORK -- Pluristem Life Systems, Inc. (OTCBB: PLRS) today announced that it has been chosen to present at the annual meeting of the American Society of Hematology on December 10th in Orlando, Florida. Hematology experts from around the world will gather to discuss the latest developments in their field. Pluristem will present how it has overcome the major barrier resulting from pre-selection and separation of cord blood early hematopoietic stem cells (HSC), and their breakthrough process that improves engraftment of Umbilical Cord Blood when treating severe blood disorders.

The current methodologies used in HSC expansion protocols apply an enrichment stage of rare subpopulation source cells defined as CD34 positive cells. These CD34 cells are pre-selected from a large and mixed population of mononuclear cells. This process results in a substantial loss of source cells and targets a cell population that may not represent the earliest extractable population of HSC.

The Pluristem developed method extracts and preserves for use a much larger number of CD34 positive cells than current methods. Pluristem's advanced approach to cell selection and separation was accomplished by using non-selected mononuclear cells (MNC) in the Company's U.S. patented three-dimensional scaffolding PluriX bioreactor. The PluriX uses flow-through co-culture techniques simulating the physiological environment within the bone marrow. The efficacy of the PluriX in expanding non-selected MNC is based upon the selective adherence of HSC and early progenitor cells from the general MNC pool to the 3-D stroma cells cultures within the PluriX system.

Zami Aberman, Pluristem CEO states, "Our ability to improve the engraftment of Umbilical Cord Blood in treating severe blood disorders, as presented recently in the ISEH conference in Minneapolis, has attracted attention in the hematology community. We are honored to have been chosen to present at this meeting of prestigious hematology experts. Our breakthrough process could lead to the wider use of Umbilical Cord Blood in bone marrow transplants and in treating various types of blood cancer benefiting 100,000 people annually."

The American Society of Hematology 48th Annual Meeting and Exposition is being held December 9-12, 2006 at the Orange County Convention Center, Orlando FL.

About Pluristem

Pluristem Life Systems, Inc. is life sciences driven company that is developing and commercializing stem cell expansion technology products for the treatment of severe blood disorders. The Company is discovering and developing cell-based therapeutics that utilizes adult stem cells expanded in a proprietary bioreactor mimicking different naturally occurring physiological environments. Pluristem expects its first products to be cell grafts that will provide an efficient and superior alternative to the standard procedure of bone marrow transplantation. Its first adult stem cell product is intended to target a critical global shortfall of matched tissue for bone marrow transplantation since bone marrow transplantation is often the only cure for patients suffering from leukemia, lymphoma, myeloma and many other hematological diseases. The Company has made a strategic decision to work only with adult stem cells since the practical use of embryonic stem cells is severely restricted by various religious, ethical and legal considerations.
