People waiting for transplant organs may soon be able to take heart, literally.
Live Science
reports that science has already been able to successfully cultivate “small-scale human organs known as organoids.” These include a mini-brain the size of a pencil eraser, beating heart muscle that is organized into chambers, 3D mini-lungs, lab-grown vaginas, a “working esophagus.” and liver cells.
Lest we feel too divine about all this, let it be known that flatworms have been “regenerating their own heads” for ages. And
zebrafish? They can “regrow their hearts.”
No need for them to tinker around in a lab.
