Blood Vessel Formation (IMAGE) Georgia Institute of Technology Caption Micro-computed angiography reconstructions of blood vessel formation in the area of the defect (top) when it experienced no mechanical force for seven weeks and (bottom) when mechanical forces were exerted on the injury site beginning after four weeks for a duration of three weeks. With delayed loading, the researchers observed a reduction in quantity and connectivity of blood vessels, but the average vessel thickness increased.
