Scientists Successfully<br />3D-Prints Heart From<br />Human Cells Professor Cal Dvir is the first person to<br />engineer and print an entire heart filled with<br />cells, blood vessels, ventricles and chambers. Dvir’s process began with a biopsy of fatty<br />tissue from the abdominal region of a patient. He and his team then reprogrammed the<br />tissue’s cells to become stem cells, which<br />then differentiated into heart cells. The cells were then<br />processed into a hydrogel<br />which served as the “ink”<br />for his 3D printer. The resulting heart is only the size<br />of a rabbit’s, but has the potential to<br />redefine heart transplantation. Dvir says the next step in his research is to train<br />the 3D-printed hearts to function properly.
