Publication number: 20190040360Abstract: In some embodiments, the present disclosure provides a method for fabricating a three-dimensional artificial cardiac patch construct. In some embodiments, such method includes the steps of coating a substrate with an organic polymer; allowing the organic polymer coating to air dry; mounting anchors on the organic polymer coating; and sterilizing the organic polymer coating and the anchors. In further embodiments, the method includes the steps of forming a biodegradable gel-based support scaffold on top of the organic polymer coating and seeding the biodegradable gel-based support scaffold with neonatal cardiac cells. In yet further embodiments, the method comprises culturing the neonatal cardiac cells in vitro to form a real cardiac layer, under culture conditions that are suitable for the cells to self-organize into a monolayer and detach from the substrate to form the three-dimensional cardiac patch.Type: ApplicationFiled: September 6, 2018Publication date: February 7, 2019Applicant: University of HoustonInventor: Ravi K.
