Human hearts created in lab

Update : 04 Oct 2013, 02:36 PM

Human hearts has been grown in test tubes. And there are hopes of bringing it in the transplants list.

The team used induced pluripotent stem cells (iPS cells)—mature cells that can be “reprogrammed” and developed into different types of cells—and induced them to become multipotential cardiovascular progenitor (MCP) cells, which are basically precursor heart cells that grow into muscle.

The scientists then”decellularised,” or removed all the cells, from a mouse heart, and attached the iPS cell-derived MCPs onto the decellularized mouse organ.

Amazingly, after about three weeks, the mouse heart had been completely rebuilt with human heart cells, and it began beating autonomously. In the near future, doctors hope to be able to save heart patients by just growing those new ones.

A team of scientists from the University of Pittsburgh School of Medicine has created lab-grown human heart tissue that can beat on its own, said on mid august of this year. “We hope our study would be used in the future to replace a piece of tissue damaged by a heart attack, or perhaps an entire organ, in patients with heart disease,” the researchers said.
