首先，打开腿骨化石之后，科学家发现了内部有一些管状分支，这些管状分支可能是骨内血管存在的地方。
First, the breaking of the fossilized leg bone revealed many small branching channels inside, which probably correspond to hollows in the bones where blood vessels were once located.
结果：在所有的鼠模型中血管平滑肌细胞都没有促进任何时相的异位骨化。
Results: Vascular smooth muscle cells did not contribute to any stage of heterotopic ossification in either mouse model.
结果：干骺端骨髓和骨骺二次骨化中心周边骨髓为含有丰富血管的红骨髓，增强后呈显著强化，且干骺端增强率较骨骺骨髓更高，但随年龄增长，两者的增强率均逐渐减低。
Results:The metaphysis and the periphery of the secondary center of ossification were red marrow. They showed marked enhancement on T 1WI. Enhancement ratio declined in both regions with age.
