MRI is a new way to track stem cell growth
4th Dec 2005, 01:02 GMT
Researchers at John Hopkins are using a new technique to track mesenchymal stem cells as they repair tissue scarred by heart attacks. Magnetic resonance imaging (MRI) is being used experimentally with animals instead of biopsies to monitor new growth of stem cells. This technique which labels cells with minuscule iron oxide particles for tracking during the MRI was presented during the November session of the American Heart Association's Scientific Sessions. The new technique is hoped to spare heart attack patients from invasive biopsies when monitoring their recovery due to stem cell transplants. According to senior investigator and veterinary radiologist Dara Kraitchman, V.M.D., Ph.D., "The technique has potentially broader applications and benefits for patient care because MRI technology is widely available and avoids the discomfort and risk of infection from biopsies, the standard method used in therapy checkups."
