Scientists said Tuesday they had used stem cells to grow human heart
tissue that contracted spontaneously in a petri dish -- marking progress
in the quest to manufacture transplant organs.
A team from the University of Pittsburgh, Pennsylvania, used
induced pluripotent stem (iPS) cells generated from human skin cells to
create precursor heart cells called MCPs. iPS cells are mature human
cells "reprogrammed" into a versatile, primitive state from which they
can be prompted to develop into any kind of cell of the body.
The primitive heart cells created in this way were attached to a mouse
heart "scaffold" from which the researchers had removed all mouse heart
cells, they wrote in the journal Nature Communications. The scaffold is a
network of non-living tissue composed of proteins and carbohydrates to
which cells adhere and grow on.
