US company invented 3D bio-printer can print living organ

Åœ — äº¬æ — ¶é — ' June 6th messages, according to foreign media reports, organ transplant that saved the lives of many people, but this technology there are not enough organs, it is difficult to avoid rejection, and other ills.

However, as the future "the advent of bio-printer", these problems will be solved. Perhaps one day, the doctor can "on-demand print" living organs, including blood vessels and complete organ.

Currently, waiting for an organ transplant patients in a suitable organ before, usually have to wait months or even years.

By the United States Organovo company developed the 3D-printer now can manufacture artery, a developer known by this equipment "print" the earliest of artery is expected in five years for cardiac bypass surgery. But heart, teeth and bones, and other more complex organs should be within 10 years is the "print".

3D bio-technological invention based on an existing printer, these technologies are currently being used to manufacture industrial parts of the 3D model.

Biological printer's different in that it does not use layers of plastic, which is the use of layers of building blocks, to manufacture real living tissue. This technology is still in its early stages, but the first prototype of the 3D-printer has been created by the end of 2009, and for the test.

3D bio-printer has two print head, a place for up to 8 million individual cells, called "bio ink"; another printable paper "bio."

The so-called bio-paper is main ingredient is water gel that can be used as the cell bracket. 3D bio-printer from the patient's own body cells, so does not result in rejection. According to reports, the machine first "print" organ or arteries of the 3D model, then a layer of cells on another layer of cells. Print out a "bio ink" cell, and then print a sheet of paper the "biological" gel.

Repeat this process until the print complete new organ.

Then, naturally generated cells began to reorganize, fusion, the formation of new blood vessels. Each vessel takes approximately one hour, but fusion together take days. Organovo CEO Keith-Murphy in the acceptance of the engineer magazine interview that, one day, just gently press the button, you can make 3D biological printer produce we need organ.
