Abstract

Objective: This study was conducted to examine the influences of supplementation of the serum substituents and available period of serum-free Vero cell conditioned media (SF-VCM) manufactured from Dulbecco's modified Eagle medium cultured with Vero cells for in vitro development of mouse preimplantation embryos.

Methods: A total of 1,099 two-cell embryos collected from imprinting control region mice were cultured in SF-VCM with 10% and 20% human follicular fluid (hFF), serum substitute supplement (SSS), and serum protein substitute (SPS). Development of embryos was observed every 24 hours. Results between different groups were analyzed by chi-square test, and considered statistically significant when P-value was less than 0.05.

Results: The rates of embryonic development cultured in SF-VCM supplemented with serum substituents were significantly higher compare with serum-free group (P < 0.05). The rates of embryonic development after 48 hours (morula≤) and 96 hours (blastocyst≤) were significantly higher in 20% SSS and 10% SPS than in 20% hFF supplementation (P < 0.05). And the rates of embryonic development after 96 hours (hatching blastocyst≤) were significantly higher in 10% SPS (94.5%) than in 20% SSS (82.6%) and 20% hFF supplementation (68.5%). The rates of embryonic development according to storage period of the SF-VCM supplemented with 10% SPS showed no significant difference between control, 2 weeks and 4 weeks group. However developmental rate in 6 weeks storage group was significantly lower than other groups.

Conclusion: The rate of embryonic development after 96 hours (hatching blastocyst≤) was significantly higher in SF-VCM supplemented with 10% SPS. And storage period of media up to 4 weeks did not affect on embryonic development.
