Scientists 3D Print Bone Tissue With Live Cells and Pre-Loaded Proteins
http://cdn.medgadget.com/wp-content/uploads/2015/07/bio-playdough.png
Printing bone tissue sounds like a great idea, but 3D printers typically use heat to melt layers together, which means that incorporating cells during the printing process is nearly impossible. **w a partnership between scientists at University of **ttingham in the UK and Cornell University in New York have developed a way of printing bone-like biocompatible material at room temperature and seeding it with special microspheres capable of releasing pre-loaded proteins.
The material is a thermoresponsive microparticulate based on PLGA (poly(lactic-co-glycolic acid)). It is similar in strength to cancellous bone tissue and can help sustain live cells in addition to the microspheres.
