Ultrasound Aligns Living Cells in Bioprinted Tissues

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process.

“We’ve reached the point where we are able to create medical products, such as knee implants, by printing living cells,” says Rohan Shirwaiker, corresponding author of a paper on the work and an associate professor in NC State’s Edward P. Fitts Department of Industrial & Systems Engineering. “But one challenge has been organizing the cells that are being printed, so that the engineered tissue more closely mimics natural tissues.
