Rabbit fetuses (14, 16, 17, 18, 20, 22, and 24 days in utero) were examined with an electron microscope, and the following results were obtained: 1. At the equatorial region of the lens, developing endothelium of the tunica vasculosa lentis was very similar in morphology to typical fibroblast. 2. Much debris of amorphous material was observed around the endothelium and fibroblast, but in general, zonule-like fine fibrils were seen near the former, whereas short collagen fibrils were observed around the latter amid amorphous material. 3. Topographically, fibroblasts lay apart from the lens equator, and few fibroblasts migrated into the posterior portion. 4. From the above data it was postulated that debris around the tunica vasculosa lentis in the vicinity of the lens equator was presumably the precursor of zonular fibrils and that fibroblasts had almost no relation to zonular formation.
对处于不同子宫内发育天数（14、16、17、18、20、22和24天）的兔胎儿进行了电子显微镜检查，结果如下：1. 在晶状体赤道区域，晶状体血管膜发育中的内皮细胞在形态上与典型的成纤维细胞非常相似。2. 在内皮细胞和成纤维细胞周围观察到大量无定形物质碎片，但一般来说，在前者附近可见带状细纤维，而在后者周围的无定形物质中观察到短胶原纤维。3. 在地形上，成纤维细胞与晶状体赤道分开，很少有成纤维细胞迁移到后部。4. 根据上述数据推测，晶状体赤道附近晶状体血管膜周围的碎片可能是带状纤维的前体，而成纤维细胞与带状纤维的形成几乎没有关系。
