A research team from the National University of Singapore (NUS) has successfully used common plant proteins to 3D-print an edible cell culture scaffold, allowing more affordable and sustainable lab-grown meat to be served on the table.
Cell culture scaffolds are typically made from synthetic or animal-based materials, which are either too expensive or inedible. In search of an alternative, the team led by Professor Huang Dejian, Deputy Head of the NUS Department of Food Science and Technology, turned to plant proteins, which are known to be biodegradable and biocompatible with animal cells. Crucially, plant proteins also satisfy common requirements for food consumption, making the resulting scaffold fit for culturing meat.
Additive manufacturing of food involves designing, pre-processing, manufacturing, and post-processing, and each step is an opportunity to create innovative foods. In Physics of Fluids, researchers identify factors that affect the print quality and shape complexity of the food created. For example, changing the printing patterns and ingredients of the initial mix or paste can affect the food’s matrix and microstructures and therefore its texture. Accounting for these features can increase food quality, improve control, and speed up printing.

Anterior cervical discectomy and fusion is widely used to treat spinal disorders. The fusion involves placing a bone graft or “cage” and/or implants where the surgically removed damaged disc was originally located to stabilize and strengthen the area. The risk factors for cage migration are multifactorial and include patient, radiological characteristics, surgical techniques and postoperative factors. A study is the first to evaluate the effect of the range of motion, cage migration and penetration using variable angle screws and cervical spine models. The plate developed and tested by the researchers provided directional stability and excellent fusion, showing promising clinical outcomes for patients with degenerative cervical spine disease.
