Bone marrow transplantation with genetically modified cells may prolong the period of cancer-free survival, suggests a study led by Dr. Vivek Rangnekar, associate director of translational research for the Markey Cancer Center at the University of Kentucky. Bone marrow, a spongy tissue inside bones, contains stem cells that produce blood cells, including leukocytes, erythrocytes and platelets. In the cover story of the July issue of Cancer Biology & Therapy, Rangnekar and his team explore the transfer of bone marrow from Par-4/SAC-transgenic donor mice to control mice as a means of transferring anti-cancer potential.
