Professor Julian Chaudhuri, a researcher in tissue engineering at Bath University, said that the inability to create working small blood vessels in the laboratory was one of the major obstacles to efforts to
create replacement organs outside the body.

The future is bright for the field, Carden believes, and the day will arrive when a patient's own cells will be used with the printing technique to
create new
replacement organs.

replacement body parts inched closer to reality with the announcement from San Diego biotech company Organovo that its
organ «printer» had
created the first artificial blood vessel made entirely from human cells, with no synthetic scaffolding.
Japanese stem cell biologist Hiromitsu Nakauchi is pioneering a technique that ultimately aims to implant human pluripotent cells into pig embryos to
create replacement human tissues and
organs.
Before scientists and engineers can realize the dream of using stem cells to
create replacements for worn out
organs and battle damaged body parts, they'll have to develop ways to grow complex three - dimensional structures in large volumes and at costs that won't bankrupt health care systems.
He added that, aside from the hope of
creating replacement tissues and
organs for patients, the work could help scientists understand how to tackle unwanted blood vessel growth, such as that found in tumours.
