Researchers at Stanford University have formulated a novel biomaterial suitable for three-dimensional (3D) bioprinting: a homogeneous composite of polycaprolactone (PCL), gelatin, and beta-tricalcium phosphate.
Collagen-based hydrogels behave similarly to the native tissue microenvironment, thus are widely used as scaffolds for encapsulating cells or molecules like growth factors. Collagen solution is an injectable liquid until it crosslinks at 37 C and physiological pH.
