How to print out a blood vessel

A tissue engineering group has succeeded in creating functional blood vessels and cardiac tissue, using a printer that dispenses cells instead of ink. The work, published this month in Tissue Engineering, is among the first to produce functional three-dimensional tissue using a printer, and a milestone on the way to the goal of printing out whole organs.

This is a significant research that it will help thousands of people escape form cardiac tissue. Rat hearts, stripped of their cells by detergents, have been used as a scaffold to engineer a bioartificial heart, which can amazingly pump a little like the original organ. One day, it will be used to repair heart damage or even generate new hearts for transplantation.
