摘要
将Ｅ１５胎鼠大脑皮质植入到成年大鼠大脑皮质３，１，２区内。对移植物进行超薄切片，电镜下轴─体突、轴─树突、轴─体突皆可见到。突触小泡多呈圆型、清亮型，有些小泡有致密的核心，表面粗糙。突触前体内小泡排列形式多样。轴─棘突触后体内有棘器。侧棘内除有棘器外，多无细胞器。移植物内除有棘器外，多无细胞器。并对移植物内突触分化发育的规律进行了探讨。
We transplanted the cerebral
cortex of E15 fetal rat into the areas 3,1,2 of adult rat brain。 Thegrafts were made into ultrathin
slides。 Under electron microscope, we found axospinal and axosomaticand axodendritic
synapses.Synaptic vesicles almost are spherical and light , Some vesicles have a densecore
and rough surface.There are some distributive forms of synaptic vesicles in
presynaptosome。Postsynaptosomes of axospinal synapo have spinal organelle。 In late ral
spine no organelles exceptspinal organelle, We also discussed the differentiation and
development regularity of synapse in grafts.
