Patent attributes
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. In some embodiments, the present disclosure pertains to a method of treatment of cardiac tissue injury in a subject in need thereof. In some embodiments, the method includes implanting the three-dimensional artificial cardiac patch described above in the injured area of the subject. In another embodiment the present disclosure provides a composition comprising the three-dimensional artificial cardiac patch described above. Additional embodiments of the present disclosure pertain to a medicament including the three-dimensional artificial cardiac patch described above.
