Using Ink Jet Technology to "Print" Organs and Tissues

Printing organs and tissues may sound like science fiction. But, our laboratory is using modified ink-jet technology to do just that. We have utilized inkjet printing technology to build heart, bone, and blood vessel tissues.

Living tissues are composed of multiple cell types arranged in a very specific order in three-dimensional space. Maintaining this structure is important to ensure that engineered tissue and organs have normal function.

Inkjet printing technology offers a possible solution to this complex problem because it allows us to precisely arrange multiple cell types and other tissue components into pre-determined sites with high precision. Multiple cells types are placed in the wells of a sterilized ink cartridge and the printer is programmed to arrange these cells in a specific order.

For military applications, we will develop an adapted ink-jet printer to provide on-site "printing" of skin for soldiers with life-threatening burns. Skin cells will be placed in the print cartridge, along with a material to support them, and will be printed directly on the wound.
