Studies from Cornell University Provide New Data on Tissue Engineering.

A new study, 'Increased mixing improves hydrogel homogeneity and quality of three-dimensional printed constructs,' is now available. "As the tissue engineering and drug delivery communities place greater emphasis on producing constructs of prescribed geometry and organization, three-dimensional printing is becoming as an increasingly important technique. While numerous tissue printing techniques have emerged, little has been done to characterize the properties of printing inks and the resultant effects on geometric fidelity, cell viability, and mechanical integrity," scientists in the United States report (see also Tissue Engineering).

"These questions have been neglected …
