Selection of oocyte cryopreservation method is a prerequisite factor for developing an effective bank system. Compared with slow freezing method, the vitrification has various advantages such as avoiding intracellular ice crustal formation. In our previous, we attempted to employ a vitrification method using ethylene glycol and an electron microscope grid for cryopreservation of mouse oocytes. However, A high incidence of spindle and chromosome abnormalities was detected in thawed oocytes after vitrification. We examined whether the addition of a cystoskeleton stabilizer Taxol , to the vitrification solution could promote the post-thawed survival and subsequent development of stored oocytes. More oocytes developed to the 4-cell (44.7% vs. 69.7%), 8-cell (31.8% vs. 64.2%), morula (24.7% vs. 54.3%), and blastocyst (20.3% vs. 49.2%) stages after the addition of Taxol to the cryoprotectant than after no addition. 21 and 26 mouse pups were born after transfer of blastocyst derived from oocytes vitrified without and with Taxol. The addition of Taxol to vitrification solution greatly promoted post-thaw preimplantation development of ICR morose oocytes.tes.
