摘　　要：应用醛复红加ＨＥ染色方法，对胎龄为９、１１、１３、１５、１７、１９ｄ（新生）的小鼠主动脉的发生过程进行了较系统地观察。结果显示，在９ｄ胎龄的小鼠，其主动脉由一层内皮细胞组成。随着胎龄的增加，动脉壁逐渐增厚，依次出现间充质细胞、平滑肌细胞和弹性纤维，进而形成具有内、中、外膜结构的主动脉。The histological method was used to study the development of the aorta in mouse embryos at 9, 11, 13, 15, 17, and 19 days (new born). The results showed that the dorsal aorta was composed only one layer endothelial cell at 9 day embryo. As the embryo growing, the aortic wall became thicker and the mesenchymal cells, smooth muscle cells and elastic fibers appeared gradually. Finally, the three layer structures of the aorta wall was all formed in a new born mouse.
