BACKGROUND: Melatonin is an endocrine hormone secreted from the pineal gland located outside the blood-brain barrier. OBJECTIVE: In this study, in vitro propagated eight-cell mouse embryos were vitrified by the Solid Surface Vitrification (SSV) method and after thawing,
their in vitro development and embryo qualities in melatonin added media were investigated. METHODS: Pronuclear stage embryos obtained from super ovulated B6CBAF1/J strain mice, were cultured until the eight-cell stage. Then these eight-cell embryos were vitrified by the SSV method
and after thawing, cultured in melatonin added media at 37°C and 5 %CO2 conditions until the blastocyst stage. RESULT: In the experimental period, in vitro embryo development rates of the control, SSV and +10-12 M melatonin groups were observed as 97%, 86%
and 93%, respectively. CONCLUSION: Our results indicated that melatonin addition slightly increased the development rates and total cell numbers of embryos vitrified by the SSV method.

More about this publication?
CryoLetters is a bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation
The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
