The goal is to make human eggs, ovarian tissue, blood vessels, even whole organs available when needed.

To get there, researchers are directly comparing slow-freezing techniques, used successfully for decades to preserve sperm and embryos, to a more rapid method of cryopreservation that transforms tissues into durable glass-like structures.

Tissue for transplants could be available within three years if trials are successful

A British research team led by the world's leading heart surgeon has grown part of a human heart from stem cells for the first time. If animal trials scheduled for later this year prove successful, replacement tissue could be used in transplants for the hundreds of thousands of people suffering from heart disease within three years.
