Capillaries of the developing cerebral cortex were examined by electron microscopy and compared with those developing in the superior rectus oculi muscle. The pericytes of cerebral vessels were found to be of very elaborate form and involved in complex 'peg and socket' relationships with endothelial cells. They were numerous and formed an almost complete investment of the endothelium. In the muscle, by contrast, pericytes were rare, although often of complex form. Cerebral capillaries were always completely and closely invested by neuropil, in marked contrast to the very loose connective tissues in the vicinity of muscle capillaries. The significance of the findings is discussed.
通过电子显微镜检查发育中的大脑皮质毛细血管，并与上直肌中发育的毛细血管进行比较。发现脑血管的周细胞形态非常精细，与内皮细胞形成复杂的“栓与窝”关系。它们数量众多，几乎完全包裹在内皮细胞周围。相比之下，在肌肉中，周细胞很少见，尽管形态常常很复杂。大脑毛细血管总是被神经毡完全且紧密地包裹着，这与肌肉毛细血管附近非常疏松的结缔组织形成明显对比。文中讨论了这些发现的意义。
