The human heart is a large muscular organ with four chambers, a septum, severalvalves, and other various parts necessary for pumping blood all around the human body. But this most vital of all organs is a product ofevolutionand has spent millions of years perfecting itself to keep humans ali...

Organoid models of early tissue development have been produced for the intestine, brain, kidney and other organs, but similar approaches for the heart have been lacking. Here we generate complex, highly structured, three-dimensional heart-forming organoi
Congenital heart defects constitute the most common human birth defect, however understanding of how these disorders originate is limited by our ability to model the human heart accurately in vitro. Here we report a method to generate developmentally rel
The process termed “excitation–contraction coupling” (ECC) consists of the repeated contraction and relaxation of the chambers of the heart, in which Ca2+is, perhaps, the most important ion involved. Ca2+that enters the cell during the plateau phase of the AP enhances Ca2+release from the ...
To our knowledge, preparation of human ventricular heart muscles has not been reported to date. With our selected MLC-2v-positive human early ventricular cells, we now are able to generate engineered human ventricular heart muscles in the current study. By combining a fixed ratio of selected ...
