Researchers use new method to deliver anti-cancer drug to suppress tumor growth
Dec 17 2020
Targeting drugs to cancer tissues is a major challenge in cancer treatment. Mesenchymal stem cells (MSCs) 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 from Tokyo University of Science have successfully modified MSCs to deliver large quantities of anti-cancer drugs in a targeted manner to developing cancer cells.
As humans evolve, cancer also evolves in parallel, making the race for finding efficient treatment methods for cancer patients challenging and constant. In addition to designing drugs for treatment, the delivery of these drugs to targeted organs is also a major challenge faced by the cancer research community.

The bull s eye: New modified stem cells can deliver drugs specifically to tumor cells
As humans evolve, cancer also evolves in parallel, making the race for finding efficient treatment methods for cancer patients challenging and constant. In addition to designing drugs for treatment, the delivery of these drugs to targeted organs is also a major challenge faced by the cancer research community.
Many research groups have tried to develop techniques to efficiently deliver anti-cancer drugs to tumors. An interesting way utilizes a distinct group of cells in our body, the mesenchymal stem cells (MSCs), which have a special ability to find and move towards tumors. This means that theoretically, we can load these tumor-homing MSCs with anti-cancer drugs and use them to hinder cancer progression. However, pilot studies show that the anti-cancer drug loading capacity of MSCs is limited, and they tend to lose their ability to target and reach tumor cells upon drug loading.
