New cell therapy aims to tame transplant dangers for cancer patients

This study is testing a new type of cell therapy for patients with blood cancers or bone marrow diseases who need a stem cell transplant from a partially matched family donor. The goal is to see if adding specially treated immune cells, called 'veto cells,' can help the donor's cells grow successfully in the patient's body while reducing the risk of a serious complication where the donor cells attack the patient's own tissues. Researchers are testing different doses of these cells in a small group of patients to find the safest and most effective amount.
