Injectable Hydrogel Repairs Heart (4 of 4) (VIDEO)
Caption
The hydrogel is made from cardiac connective tissue that is stripped of heart muscle cells through a cleansing process, freeze-dried and milled into powder form, and then liquefied into a fluid that can be easily injected into the heart. Once it hits body temperature, the liquid turns into a semi-solid, porous gel that encourages cells to repopulate areas of damaged cardiac tissue and to preserve heart function. This image relates to a paper that appeared in the Feb. 20, 2013, issue of Science Translational Medicine, published by AAAS. The paper, by Sonya Seif-Naraghi at University of California, San Diego in La Jolla, Calif., and colleagues was titled, “Safety and Efficacy of an Injectable Extracellular Matrix Hydrogel for Treating Myocardial Infarction.”
