New modified stem cells can deliver drugs specifically to tumor cells

Targeting drugs to cancer tissues is a major challenge in cancer treatment. Células-tronco mesenquimais (MSC) are known for their ability to find and target tumor cells in the body, but using MSCs for drug delivery has been tricky, because upon loading with drugs, MSCs lose their viability and migratory ability. Now, researchers have successfully modified MSCs to deliver large quantities of anti-cancer drugs in a targeted manner to developing cancer cells.
