MATERIALS AND METHODS FOR TREATING CRITICALLY SIZED DEFECTS IN MOUSE BONE

摘要

Scaffolds equipped to include biologically active reagents such as proteins sized and engineered specifically for use in a mouse were made and implanted into mice. The scaffold was specifically designed for use in a mouse femoral critical sized defect Scaffolds. Special care was taken when casting these scaffolds to ensure that the material used to form the body of the scaffold did not include defects such as a large number of macroscopic holes that could compromise the structural integrity of these very small devices. Some of these scaffolds include a hollow center that accommodate a rod that ran the longitudinal length of the scaffold extending into the adjacent bone to anchor the scaffold to the bone. Scaffold also include at least one channel that extended from the outside of the structure towards its center and could be hold a liquid or paste comprising for example exogenous BMP-2.
