Simple Science @Heart: Magnetic particles in cells help track heart treatments

Published: 3:00 pm CDT, July 10, 2012

Tiny magnetic particles are helping doctors track cells in the body.

With stem cell therapy, doctors can adapt blood cells to fight disease. But it’s hard to tell exactly where cells go and how many go where they are supposed to. Safely tracking them with magnets would help scientists better understand how new cell therapies combat heart disease.

Researchers injected several people with cells containing magnetic particles. MRI scans were then able to pick up the magnetic signal from these cells and track their movement through the body. The magnetically labeled cells moved like normal ones and were safe for study participants. However, magnetizing cells isn’t quite ready for prime time – the researchers say more tests are needed before researchers can use this technique regularly.

    For almost 3 years, I kept going to dorcots who kept insisting that all I had was clinical depression and ADHD. For 3 years I kept taking elephant-sized dosages of anti-depressants and Ritalin. The symptoms kept getting worse. Finally got a job that provided health insurance, so the first time I had a seizure after that, i went straight to the ER. only then, after listening to me, the ER dorcots ordered a CAT-Scan and a MRI. And what did they find? A big, honking brain tumor!!!! Big as 2 Altoids cans put side-by-side!!! Seems I was just a hair away from being dead!!!! And now, thanks to the dorcots who wouldnt listen, I have had to deal with all manner of complications, seizures, a severe heart attack. My academic and career goals have gone to hell, and I am working a joe-job, that allows me the luxury of living below the poverty line!!!!! :( :(
