Nanoparticles target and kill cancer stem cells that drive tumor growth

RATE THIS! +22
Posted in Medicine on 16th Jun, 2015 12:39 AM by AlexMuller

Many cancer patients survive treatment only to have a recurrence within a few years. Recurrences and tumor spreading are likely due to cancer stem cells that can be tough to kill with conventional cancer drugs. But now researchers have designed nanoparticles that specifically target these hardy cells to deliver a drug.

 

The nanoparticle treatment, reported in the journal ACS Nano, worked far better than the drug alone in mice. Anti-cancer drugs can often shrink tumors but don't kill cancer stem cells (CSCs). Although CSCs might only make up a small part of a tumor, their resistance to drugs allows them to persist. They can then cause a tumor to regrow or spread cancerous cells throughout the body. Xiaoming He and colleagues wanted to develop a nanoparticle system to overcome these cells' defenses.

It is good to see that investments in cancer research over the years are now producing new and better treatments - nanotechnology is making a great contributions as this example of targeting CSCs. Reply
