The Myocardial Regeneration Lab at Worcester Polytechnic Institute focuses broadly on cardiovascular regeneration techniques, but more specifically on developing better ways to deliver cells to damaged myocardium as well as better techniques to analyze cardiac mechanics. We have developed biological sutures made from discrete fibrin microthreads that can be used to seed cells and deliver them to cardiac tissue. Additionally, we have developed a particle tracking method that can be used to determine regional cardiac mechanics as well as quantify contractile strains produced by contracting cardiac cells.
