Abstract
The ultimate goal of cardiac tissue engineering is to generate new muscle to repair or replace the damaged heart. This requires advances in stem cell technologies to differentiate billions of cardiomyocytes, together with advanced biofabrication approaches such as 3D bioprinting to achieve the requisite structure and contractile function. In this concise review, we cover recent progress in 3D bioprinting of cardiac tissue using pluripotent stem cell-derived cardiomyocytes, key design criteria for engineering aligned cardiac tissues, and ongoing challenges in the field that must be addressed to realize this goal.

Abstract
Here we developed a simplified model of the human heart, similar that observed in embryonic development where the heart first starts as a contractile linear tube. To this end, we created a bioinspired model of the human heart tube scaled ~10x larger, consisting of a collagen tube fabricated with high fidelity using freeform reversible of embedding of suspended hydrogels (FRESH) 3D bioprinting. The collagen tubes were cellularized using human stem cell-derived cardiomyocytes and cardiac fibroblasts via a rapid casting approach, with synchronous contractions ~3-4 days after fabrication and maintained for up to one month. Immunofluorescent staining confirmed dense, interconnected networks of sarcomeric α-actinin-positive cardiomyocytes. Electrophysiology was assessed using calcium imaging and demonstrated anisotropic calcium wave propagation along the heart tube with a conduction velocity of ~5 cm/s. Contractility and basic pump function were demonstrated by tracking the movement of fluorescent beads within the lumen to estimate fluid displacement and bead velocity. Results show the ability to displace fluid, but the simple linear design and lack of valves limited mean bead displacement. In summary, we have 3D bioprinted a contractile human heart tube as an initial step toward organ engineering by mimicking the simplified structure observed at early developmental time points.
