We observed the structural changes in blood vessels entering the growth plates of the femur and tibia of rats during growth using scanning electron microscopy. The penetrating vessels had blind endings which were bulbous at a time when rats showed rapid skeletal development. With subsequent slowing of development, the density of the vessels decreased and the blind endings became short stumps. These changes were more prominent in the proximal femur than in the distal femur and proximal tibia. The present study indicates an intimate relation between endochondral ossification in the growth plate and the structure of the penetrating vessels.
我们使用扫描电子显微镜观察了大鼠生长过程中进入股骨和胫骨生长板的血管的结构变化。在大鼠骨骼快速发育时期，穿透性血管具有盲端，这些盲端呈球状。随着发育随后放缓，血管密度降低，盲端变成短残端。这些变化在股骨近端比在股骨远端和胫骨近端更为明显。本研究表明生长板中的软骨内骨化与穿透性血管的结构之间存在密切关系。
