Prof. Michal Neeman and Dr. Batya Cohen of the Weizmann Institute’s Biological Regulation Department, along with Ph.D. students Keren Ziv and Vicki Plaks and colleagues, have now developed genetically modified mice that carry a promising candidate reporter named ferritin, which could circumvent these problems. Ferritin works by sequestering iron from cells. When it is overexpressed, iron uptake increases, causing signal changes in the surrounding environment that can be detected by MRI, without the need to administer an additional substance.
As recently described in the journal Nature Medicine, ferritin has so far successfully broadcast live reports via MRI detection from the liver, endothelial cells and even during fetal development in pregnant mice, without the need for additional substances.
