Spheroids of cardiomyocytes derived from human-induced pluripotent stem cells improve recovery from myocardial injury in mice. Am J Physiol Heart Circ Physiol 315: H327-H339, 2018. First published April 6, 2018; doi:10.1152/ajpheart.00688.2017. The New & Noteworthy statement, which should appear in the Abstract, was omitted. It should read as follows (and is correct online): NEW & NOTEWORTHY Spheroids fuse in culture to produce structures with uniformly distributed cells. Furthermore, human cardiac lineage-induced pluripotent stem cells in cardiomyocytes in adjacent fused spheroids became electromechanically coupled as the fusions matured in vitro, and when the spheroids were combined with a biological matrix and administered as a patch over the infarcted region of mouse hearts, the engraftment rate exceeded 25%, and the treatment was associated with significant improvements in cardiac function via a paracrine mechanism, where exosomes released from the spheroid patch.
