The manner in which heart muscles could be restructured by using parthenogenic stem cells was shown by scientists.
Parthenogenesis is a form of asexual reproduction, during which unfertilized eggs begin to develop as if they had been fertilized.
Dartmouth Professor Makes Case for Ethically Universal Stem Cell Lines
Human embryonic stem cells (hESC), those very young cells that are a biological blank slate, have the potential to become more specialized,

It occurs naturally in many plants and a few invertebrate (some bees, scorpions, parasitic wasps) and vertebrate animals (some fish, reptiles, and amphibians), but does not occur naturally in mammals.
In 2007, researchers were able to chemically induce human egg cells to undergo parthenogenesis.
The resulting parthenogenote has properties similar to an embryo, but cannot develop further.

The first comprehensive model of human heart development using observations of living foetal hearts was created by researchers.
Wolfram Zimmerman and colleagues at Georg-August-Universitat Gottingen in Gottingen, Germany, demonstrated that cells from the parthenogenote function as embryonic stem cells and maintain the capacity to develop into different types of tissue.
Further, they used parthenogenic stem cells to make cardiomyocytes and engineered heart muscle (myocardium) that exhibited the structural and functional properties of normal myocardium.
The engineered myocardium could then be used to engraft the mice that had contributed the eggs for parthenogenesis.
These studies demonstrate that parthenogenic stem cells can be used for tissue engineering.
The findings are published in the Journal of Clinical Investigation.
