In what may be a critical breakthrough for creating artificial organs, Harvard researchers say they have created tissue interlaced with blood vessels.

Using a custom-built four-head 3D printer and a “disappearing” ink, materials scientist Jennifer Lewis and her team created a patch of tissue containing skin cells and biological structural material interwoven with blood-vessel-like structuresReported by the team in Advanced Materials, the tissue is the first made through 3D printing to include potentially functional blood vessels embedded among multiple, patterned cell types.

In recent years, researchers have made impressive progress in building tissues and organ-like structures in the lab. Thin artificial tissues, such as a trachea grown from a patient’s own cells, are already being used to treat patients (see “…
