摘　　要：本文用扫描电镜对10例不同胎龄人(12～38周)胎儿肝表面间皮进行了观察。研究结果发现各例间皮细胞表面都有微绒毛,但其长度、粗细和分布的疏密程度有所不同,经测算不同胎龄之微绒毛长度:12周时为1.00μm,以后逐渐增长至32周时为1.80μm,而38周者又减低为1.20μm,直径变化在0.10～0.19μm间。每平方微米的微绒毛数随胎龄增加而增多。本文对不同胎龄间皮之间的差异进行了描述,并联系其机能意义进行了讨论。The hepatic mesothelial cells Of 10 fetuses with different fetal—age were observed with SEM. It was found that all the free surfaces of mesothelial cells were covered with microvilli. In different fetal—age, these microvilli vary in length, width, density and distribution. The length changes with fetal—age, ranging from 1.00μm (12 weeks) to 1.80 μm(32 weeks), however, in the period of 38 weeks, it is 1.20μm; its width vary from 0.10 to 0.19μm. The number of microvilli in a square micrometer also increases with fetal—age.
