Oganovo is a company based in San Diego, California.

Their latest science invention is a technology (novogen) which allows living tissue cells to be assembled into patterns and complex structures, such as organs.

Organovo has partnered with Invetech. a company based in Australia, to develop a bio-printer.

The device prints (places) human cells in a three-dimensional matrix to construct human tissue.

"Building human organs cell-by-cell was considered science fiction not that long ago," says Fred Davis of Invetech.

Currently, the bio-printer can grow blood vessels. It is anticipated that within five years the device will construct arteries and by 2020 sophisticated organs will be built by the device.
