This Beating Sesame Seed-Sized 'Human Heart' Grew Itself in a Lab
23 MAY 2021 Scientists have successfully grown a bundle of human stem cells into a tiny artificial "heart" the size of a sesame seed. The pulsating mass is the first self-organizing miniature organ to resemble the human heart, including a hollow chamber enclosed by a wall of cardiac-like tissue. Simple heart-like organs, or cardioids, have been built in the lab before, but only using a scaffold, a mold, or a matrix for the cells to assemble around. This new cardioid model spontaneously constructed itself. All scientists had to do was coax the pluripotent stem cells in their dish using six...
