To improve in vitro embryonic cell development, this study was desigend to culture in vitro fertilized early embryos of mouse in two different systems; conditioned medium alone and ampullary cells co-culture. Thirty two of 83 embryos(38.6%) were blocked in the 2 cell stage by co-culture, as compared to forty of 42 embryos(95.2%) in control group for 24hours culture. And all the embryonic cells cultured for conditioned medium alone were blocked for 48 hours culture. Twenty seven of 46 embryos (58.7 %) which overcome culture block in 2 cell stage by cocultured were developed morular and expanded blastocyst, and ninteen of 46 embryos(26.1 %) underwent hatching for 96 hours culture. The cellular fragmented rates for embryo were 26.2% in medium alone; 10 fragmented blastomere were graded mild status and 1 fragmented blastomere in severe status. On the other hand, the fragmented rate for 48 hours co-cultured were 15.7%03/83); 8 fragmented embryos were graded mild status, moderate status in 3 fragmented embryos and severe in 2 fragmented embryos respectively. In conclusion, the co-culture of embryos with ampullary cells is good to improve quality of embryos and overcome of culture block as well as development of cell cleavage.
