From spare parts and guns, 3D printing is becoming a promising approach in engineering personalized tissues and organs in cases when regeneration of cells is difficult and replacement of damaged ones is expensive.
For the first time, the scientists used fully personalised non-supplemented materials as bio-inks for 3D printing, the research paper explains. The bio-inks do not provoke an immune response, thereby minimising complications after transplantation.
Scientists extracted fatty tissue from the patient and processed them to form diverse personalised bio-inks to 3D print the heart, complete with cells, blood vessels, ventricles, and chambers.
