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