Stem cell can be isolated from the the bone marrow and adipose tissue in the abdomen that are capable of forming new blood vessels and heart muscle cells. The cell number is so small in the tissues that the cells should be grown for several weeks before there is enough for the treatment of patients.

We have conducted three clinical stem cell therapy studies in which patients with coronary artery disease havebeen treated with their own mesenchymal stem cells from either the bone marrow or adipose tissue. Encouraging results are available from two studies and there is ongoing follow-up in the third study. Treatments with stem cells have in all previous studies been without any side effects.

During the course of the SCIENCE study a total of 138 patients with heart failure will be included and treated in a so-called blinded placebo-controlled design. This means that 92 patients will receive stem cells and 46 patients placebo (inactive medication, saline). Choice of treatment will be done by drawing lots. The study is carried out by an international collaboration between cardiac centers in Denmark, Poland, Germany, Netherlands, Austria and Sloveniaand the industrial partners Terumo BCT and COOK Tegentec.
