The uptake and the realease of 3 H-glycine and 3H-aspartic acid in 22 specimens of fresh human embryonic retina were examined by in vitro experimental methods of a radioisotope tracing and an autoradiography so as to understand the emerging time for functional differentiation of neurons of human embryonic retina.

本文应用同位素示踪和放射自显影技术,观察了新鲜人胚胎22例视网膜神经元体外摄取和释放~3H-甘氨酸和~3H-天门冬氨酸功能的出现。结果表明,14~15周人胚胎视网膜已具有摄取和K~+刺激、Ca~(++)依赖性释放外源性~3H-甘氨酸和~3H-天门冬氨酸的能力。摄取和~3H-甘氨酸的细胞是视网膜内核层最深层的细胞,摄取和蓄积~3H-天门冬氨酸的细胞是内核层中部和外核层的部份细胞,根据细胞形态和所在位置,我们认为这些细胞分别是发育中的无长突细胞,双极细胞和视锥细胞。此外,在~3H-天门冬氨酸的放射自显影图像中,可见视网膜的外核层、内网层和神经纤维层中有条索状银粒分布,这可能是Müller细胞被标记的结果。

The development of the three sets of neurones and the pigment epithelium of the retina of the human embryos and fetuses, dating from the seventh week to term, were studied at histological and ultrastructural levels.The discs in the outer segments of the rods and cones were recognized at the seventh month. The newly formed discs were not orderly arranged. At term, the discs became parallel to each other and perpendicular to the long axis of the outer segment. At nineth month, no phagocytised discs were seen within...

The development of the three sets of neurones and the pigment epithelium of the retina of the human embryos and fetuses, dating from the seventh week to term, were studied at histological and ultrastructural levels.The discs in the outer segments of the rods and cones were recognized at the seventh month. The newly formed discs were not orderly arranged. At term, the discs became parallel to each other and perpendicular to the long axis of the outer segment. At nineth month, no phagocytised discs were seen within the pigment epithelium, but they were discerned inside the cytoplasms of the pigment epithelia of the term fetuses.
