A tissue scaffold is a broad term for a biomaterial that guides and promotes tissue healing. Think of an injury as an empty plot of land. If you want someone to live there, they have to build the house, electrical connections, and water pipes before they can move in. A scaffold is like having the house and infrastructure in place, so people can move in much faster. The scaffold provides cells with a similar infrastructure. These can be made of many polymers, including collagen, polylactic acid, and others.

Should the polymer structure be dense (high % crystallinity) or less dense (low % or amorphous)? Explain your answer in a couple sentences.
