A Look at the State of Tissue Scaffolding

Progress continues in the development of biochemically active scaffolding to sculpt and guide tissue regeneration: here, ScienceDaily looks at a scaffold "made from soluble fibers, which may help humans replace lost or missing bone. With more research, [it] could also serve as the basic technology for regenerating other types of human tissues, including muscle, arteries, and skin. ... The bioactive agents that spur bone and tissue to regenerate are available to us. The problem is that no technology has been able to effectively deliver them to the tissue surrounding that missing bone. [This] artificial and flexible scaffolding connects tissues together as it releases growth-stimulating drugs to the place where new bone or tissue is needed - like the scaffolding that surrounds an existing building when additions to that building are made. ... The [scaffold material] could be used to restore missing bone in a limb lost in an accident, or repair receded jawbones necessary to secure dental implants ... The scaffold can be shaped so the bone will grow into the proper form. After a period of time, the fibers can be programmed to dissolve, leaving no trace."
