Gold nanofibers help cardiac tissue engineering capabilities dramatically

Heart tissue sustains irreparable damage in the wake of a heart attack. Because cells in the heart cannot multiply and the cardiac muscle contains few stem cells, the tissue is unable to repair itself — it becomes fibrotic and cannot contract properly.

In their search for innovative methods to restore heart function, scientists have been exploring cardiac "patches" that could be transplanted into the body to replace damaged heart tissue. Now, in his Tissue Engineering and Regenerative Medicine Laboratory, Dr. Tal Dvir and his PhD student Michal Shevach of Tel Aviv University's Department of Molecular Microbiology and Biotechnology and the Center for Nanoscience and Nanotechnology, together with their colleagues, are literally setting a gold standard in cardiac tissue engineering.
