By now you've probably heard about 3D bio printing, a bioengineering technique for literally building functional replacement tissue and eventually organs. (Read an earlier blog of ours on the subject.) While still in the early stages of development in terms of actually producing a human organ for transplant, the technology is advancing and critical problems are being met with innovative solutions. In the July issue of Nature Materials, University of Pennsylvania scientists, in conjunction with MIT and Harvard researchers, published an article documenting their success creating a blood vessel network using sugar.
