Abstract
A matrix and a method for preparing it are provided to support the growth of tissue, such as bone, cartilage or soft tissue. A polysaccharide is reacted with an oxidizing agent to open sugar rings on the polysaccharide to form aldehyde groups. The aldehyde groups are reacted to form covalent linkages to collagen.
