Watch Lab-Grown Heart Tissue Beat On Its Own [Video] | Popular Science: Using various enzymes and special cleansing detergents, the researchers stripped a mouse heart of all its cells to create a scaffold for induced pluripotent stem cells (iPS cells), adult human cells that are reprogrammed to act like embryonic cells. They treated the iPS cells taken from a skin biopsy to become multipotential cardiovascular progenitor (MCP) cells, the precursor cells that can become any of the three types of cells found in the heart...
After a period of a few weeks, the human cells had repopulated the mouse heart, and it began beating at a rate of 40 to 50 beats per minute.
