Why does cancer spread to the spine? Newly discovered stem cells might be the key
In this episode:
00:45 A new insight into cancers' selective spreadCancer cells can spread to bones in the late stages of disease and in many cancers, cells actually preferentially metastasise to the spine. The reason for this has been a puzzle to researchers for years, but now a team has found a new kind of stem cell that may be involved in this process. The stem cell is found in mice and humans and could represent a clinical target in the treatment of cancer.
