Bioprinting Engineered Tissues Containing Intricate Small-Scale Vascular Networks

The generation of appropriately dense and small-scale capillary networks remains the major roadblock in the progression of tissue engineering, and this has been the case for many years now. Researchers have established the recipes needed to generate functional tissue structures for many organs, from lungs to liver, but in order to grow more than millimeter-thick tissue sections, blood vessels are needed to carry nutrients and oxygen to the inner cells. Unfortunately, growing blood vessels is a very challenging problem, and up until quite recently no-one was even getting close to a viable solution that didn’t involve taking existing tissues and decellularizing them to obtain a preexisting extracellular matrix structure with a capillary network. This matrix can then be repopulated with the required cell types
