| Summary: | Background and Aims: Mitochondria have a pivotal role in the quality of embryos and good development to a healthy embryo pregnancy. Also, mitochondrial dysfunction increases during the aging of the embryos. But there is still a debate about the main cause of mitochondrial dysfunction in the aged embryos. We investigate that effect of microtubule stabilizer (MTS) as Taxol, EpD and microtubule disturber (MTD) as VNB in the preimplantation embryo of the mouse. Method: We performed preimplantation embryo culture with MTS and MTD. Then we assess development ratio and mitochondria functional activity between control and MTS and MTD. We performed comparable analysis of mitochondrial motility between MTS treated and MTD treated embryos by confocal live imaging. Results: In the MTS treated embryos, well-developed embryos with microtubules formation were present in the ooplasm. However, in the MTD treated embryos group, less development and poor microtubule polymer formation was observed in the ooplasm. Microtubules was also demonstrated by depolymerization and the clustering form in the ooplasm of MTD treated embryos. The high dynamic movement of the cytoskeleton with a mitochondrion compared to the MTD treated embryos. Conclusion: Our data suggest that the new function of MTS as Taxol, EpD shows promoting competence of embryo development with enhanced activity of a mitochondrial function. Therefore, MTS is useful as a supplement in vitro culture media of embryos. |
