Single cell RT-PCR on mouse embryos: a general approach for developmental biology.

I-13: Transcriptome Dynamics of Human and Mouse Preimplantation Embryos Revealed by Single Cell RNA-Sequencing

Background: Mammalian preimplantation development is a complex process involving dramatic changes in the transcriptional architecture. However, it is still unclear about the crucial transcriptional network and key hub genes that regulate the proceeding of preimplantation embryos. Materials and Methods: Through single-cell RNAsequencing (RNA-seq) of both human and mouse preimplantation embryos, ...

Mouse Oocytes and Embryos Cryotop-vitrification Using Low Concentrated Solutions: Effects on Meiotic Spindle, Genetic Material Array and Developmental Ability

P-107: The Effects of Cryotop Vitrification on Heat Shock Protein 72 Expression in Mouse 2-Cell Embryos by Nested Quantitative PCR

Background: The aim of the study was to compare the effects of two different concentrations of cryoprotectants by Cryotop vitrification on survival and Heat shock protein 72 (Hspa1a) expression of two-cell mouse embryos. Materials and Methods: Different cryoprotectants’ concentrations of the combination of dimethyl sulfoxide (DMSO) and ethylene glycol (EG) were used and compared with each other...

P-30: Developmental Capacity and Blastocyst Formation of Thawed Tetrahedral Versus Non-Tetrahedral 4-cell Stage Mouse Embryos After Vitrification

Background: It was reported in a literature that approximately one third of the 4-cell stage embryos did not exhibit a tetrahedral shape. Non-tetrahedral embryos showed a lower in vitro developmental potential than tetrahedral embryos. Recently vitrification technology has been widely employed for embryo cryopreservation. The objective of this study was to prove our hypothesis that vitrified - ...

Determination the Effects of Epidermal Growth Factor on Developmental Rates of Pre-Implantation Mouse Embryo

Purpose: To determine the effects of different doses of addition of exogenous epidermal growth factor (EGF) on development of pre-implantation mouse embryo. Materials and Methods: Mouse zygotes, two cell, 8 cell any morulae were collected from superovulated NMRI mice 24, 48, 64 and 80 hrs after hCG injection, respectively. The obtained embryos were cultured on medium alone, medium with 1, 4 an...
