Questions & Answers

Q: What is the primary focus of the researchers' work in the lab?

The researchers' primary focus is on manufacturing human tissues, particularly cardiac tissues, using 3D bioprinting techniques.

Q: How is the ink used in 3D bioprinting different from traditional 3D printing materials?

Unlike traditional 3D printing materials that cure into solid plastic, the ink used in 3D bioprinting is a soft biocompatible material containing living cells. It can be directly patterned into a predetermined tissue architecture.

Q: Why is manufacturing a human heart challenging?

Manufacturing a human heart is challenging because it consists of over 10 billion cells and two dozen cell types arranged in a complex 3D structure. It requires a significantly larger number of cells and precision to create a functional and beating organ.

Q: Apart from cells, what other aspects do the researchers focus on in their work?

In addition to cells, the researchers also work on developing new 3D printing hardware to manufacture human tissues at larger scales, faster speeds, and higher resolutions. They also collaborate with surgical colleagues to understand the requirements for implanting the tissues.

Summary & Key Takeaways

  • The researchers are using 3D bioprinting to create human tissues, specifically focusing on cardiac tissues for treating cardiac diseases.

  • They are using a soft biocompatible material that contains living cells as ink to pattern the tissue in a precise three-dimensional architecture.

  • The team aims to build a pipeline of enabling trillions of cells, develop new 3D printing hardware, and collaborate with surgical colleagues to meet the needs of implanting the tissues.
