1. Production of nuclear transferred GGC.:Attempts were made to produce nuclear transferred gonadal germ cells (GGCs) using karyoplast produced from fibroblast. Karyoplasts were produced by using centrifuging fibroblast at 10,000 g 1 hour in the presence of 0.1% cytochalasin B. Average diameter of the karyoplasts were 10% smaller tcompared with intact fibroblast. Six nuclear transferred GGCs were produced using karyoplasts by electrofusion.2. Production of intra-Genus nuclear transferred GGCs.Attempts were made to produce intra-genus nuclear transferred GGC using chicken and quail. After electrofusion, 0.5-1.2 % of the nuclear GGCs was produced.3. Effects of soft X exposure on the migrating ability of primordial germ cells.Effects of soft X exposure on the migrating ability of primordial germ cells were examined. Results showed that the PGCs retain their migration ability toward gonadal ridge after transfer even after soft exposure.

1。产生核转移的GGC。：使用由成纤维细胞产生的核成形体产生核转移的性腺生殖细胞（GGC）。在存在0.1％细胞切氏蛋白酶的情况下，使用10,000 g的成纤维细胞以10,000 g的速度使用核细胞生产核成形剂。核成形棒的平均直径为10％的them the，该直径与完整的成纤维细胞相对较小。使用核成形物通过电渗封产生了六个核转移的GGC.2。产生核内核转移的GGC。进行了自发者使用鸡和鹌鹑生产核内核转移的GGC。电掩埋后，产生了0.5-1.2％的核GGC.3。 X暴露对原始生殖细胞的迁移能力的影响。软X暴露对原始生殖细胞迁移能力的影响。结果表明，即使在软暴露后，PGCS在转移后仍保留其向性腺脊的迁移能力。
