Researchers use sperm to deliver cancer drugs to tumors
Chemotherapy has a lot of terrible side effects and that's partly because the drugs being used to fight cancer also attack healthy cells. Figuring out a way to deliver drugs to tumors without affecting healthy tissue is a challenge and a problem that researchers are trying to solve. One group working on this problem, New Scientist reports, is a team at the Leibniz Institute for Solid State and Materials Research Dresden and in a recent study, they showed that sperm could be turned into an effective drug delivery tool.
Sperm offer quite a lot of benefits when it comes to delivering drugs. They're naturally mobile, they can encase the drug so that it doesn't get diluted by body fluids or leak out and they protect the drug from enzymes that can break them down. They also don't cause immune responses like other other cell types -- bacteria, for example -- and they don't duplicate and form unwanted colonies.The researchers first showed that just soaking sperm in a drug, in this case a cancer treatment called d...
