Stem cell shield 'could protect cancer patients'

摘要

The trial is being conducted on patients with brain cancer. It may be possible to use "stem cell shielding" to protect the body from the damaging effects of chemotherapy, eariy results from a US trial suggest. Chemotherapy drugs try to kill rapidly dividing cancer cells, but they can also affect other healthy tissues such as bone marrow. A study, in Science Translational Medicine, used genetically modified stem cells to protect the bone marrow. Cancer Research UK said it was a "completely new approach". The body constantly churns out new blood cells in the hollow spaces inside bone. However, bone marrow is incredibly susceptible to chemotherapy.
