Researchers have developed a way of assembling organic molecules into complex tubular tissue-like structures without the use of moulds or techniques like 3-D printing. The study describes how peptides and proteins can be used to create materials that exhibit dynamic behaviors found in biological tissues like growth, morphogenesis, and healing.
The method uses solutions of peptide and protein molecules that, upon touching each other, self-assemble to form a dynamic tissue at the point at which they meet. As the material assembles itself it can be easily guided to grow into complex shapes.
This discovery could lead to the engineering of tissues like veins, arteries, or even the blood-brain barrier,...
