Some Romanian IT-scientists from Timisoara have created a 3D bio-printer that could be able to recreate human organs. The first test has already been done, the first attempt being the printing of an ear made of stem cells and collagen.
Lavinia Iliesi, biologist specialist in oncogenic cell cultures:
"These cells are kept in a cell bank, then thawed and cultured."
Călin Brandabur, IT specialist:
"We deposit the biological material, as a structure, layer by layer, following a three-dimensional project, which comes either from the computer tomography or from a three-dimensional modeling. We also introduce stem cells in strategic points. Being fed, they will begin to take on the structural and anatomical functions of the printed form."
After the cultivation of stem cells, they are used for printing, together with another biological material - collagen. The intelligent bio-printer was built by a team of IT-ists from our country and because the organs are created with the stem cells collected from the patient, there are few chances that the body will reject them after the transplant.
