Researchers at CU Boulder have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells.

Published today in Cell Reports, the research marks a major step toward successfully developing a universal vaccine for not only COVID-19, but also potentially for influenza, HIV and other deadly global viruses.

“We’ve developed a predictive tool that can tell you ahead of time which antibodies are going to be effective against circulating strains of virus,” said lead author Timothy Whitehead, associate professor of chemical and biological engineering. “But the implications for this technology are more profound: If you can predict what the variants will be in a given season, you could get vaccinated to match the sequence that will occur and short-circuit this seasonal variation.”


Researchers have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells, which could inform the development of more effective booster vaccines and tailored antibody treatments for patients with COVID-19.

Mechanical loading is an important cue for directing stem cell fate and engineered tissue formation in vitro. Stem cells cultured on 2-dimensional (D) substrates and in 3D scaffolds have been shown to differentiate toward bone, tendon, cartilage, ligament, and skeletal muscle lineages depending on their exposure to mechanical stimuli. To apply this mechanical stimulus in vitro, mechanical bioreactors are needed. However, current bioreactor systems are challenged by their high cost, limited ability for customization, and lack of force measurement capabilities. We demonstrate the use of 3-dimensional printing (3DP) technology to design and fabricate a low-cost custom bioreactor system that can be used to apply controlled mechanical stimuli to cells in culture and measure the mechanical properties of small soft tissues. The results of our in vitro studies and mechanical evaluations show that 3DP technology is feasible as a platform for developing a low-cost, customizable, and multifunctional mechanical bioreactor system.

• 3DP technology was used to print a multifunctional bioreactor system/tensile load frame for a fraction of the cost of commercial systems.

• The system mechanically stimulated cells in culture and evaluated the mechanical properties of soft tissues.

Scientists at the Catholic University of Korea and Asan Medical Center have 3D printed a novel device that could be used to stabilize Acute Liver Failure (ALF) patients as they wait for a life-saving organ donation.

Composed of a 3D printed container and semipermeable membrane, the team’s implant allows for the rapid delivery of the drugs needed to save those in danger of succumbing to ALF. Once implanted, the device also acts as a ‘bioartificial support system,’ functioning as the patient’s liver while reducing any dysfunction caused to their other internal organs, keeping them alive until a transplant becomes available.
