TORONTO, February 9, 2017<\/strong> \u2013 Matters of the heart can be complicated, but York University scientists have found a way to create 3D heart tissue that beats in synchronized harmony, like a heart in love, that will lead to better understanding of cardiac health, and improved treatments.<\/p>\n

York U chemistry Professor Muhammad Yousaf and his team of grad students have devised a way to stick three different types of cardiac cells together, like Velcro, to make heart tissue that beats as one.<\/p>\n

Until now, most 2D and 3D in vitro<\/em> tissue did not beat in harmony and required scaffolding for the cells to hold onto and grow, causing limitations. In this research, Yousaf and his team made a scaffold free beating tissue out of three cell types found in the heart \u2013 contractile cardiac muscle cells, connective tissue cells and vascular cells.<\/p>\n

The researchers believe this is the first 3D in vitro<\/em> cardiac tissue with three cell types that can beat together as one entity rather than at different intervals.<\/p>\n

\u201cThis breakthrough will allow better and earlier drug testing, and potentially eliminate harmful or toxic medications sooner,\u201d said Yousaf of York U\u2019s Faculty of Science.<\/p>\n

In addition, the substance used to stick cells together (ViaGlue), will provide researchers with tools to create and test 3D in vitro<\/em> cardiac tissue in their own labs to study heart disease and issues with transplantation. Cardiovascular associated diseases are the leading cause of death globally and are responsible for 40 per cent of deaths in North America.<\/p>\n
