Some scientists hope to exploit the phenomenon to get around ethical concerns surrounding embryonic stem cell research.

The result — the second such finding in the past year — suggests that similar cells from human testicles might have similar powers, paving the way to creating replacement tissue for men who have suffered damage from heart attacks or other injuries and avoiding some of the controversy surrounding embryonic stem cells (ESC).

Embryonic development in mammals begins with the division of the fertilized egg, which is then followed by several further rounds of division to form the blastocyst, a sphere of cells made up of two layers of cells surrounding a fluid - filled cavity.

Figure 1: The blastocyst is a hollow sphere made of approximately 150 cells and contains three distinct areas: the trophoblast, which is the surrounding outer layer that contains the trophoblast stem cells and later becomes the placenta, the blastocoel, which is a fluid - filled cavity within the blastocyst, and the inner cell mass, also known as the embryoblast, which can become the embryo proper, or fetus, and is where human embryonic stem cells are isolated from.
