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, ...

Detection of human novel developmental genes in cDNA derived from replicate individual preimplantation embryos.

We have constructed amplified cDNA preparations from replicate samples of human oocytes and individual preimplantation embryos. Differential display of the cDNA preparations shows disparate patterns of gene expression in the individual embryos at all stages of preimplantation development. The variation in patterns of genes expressed is in part due to the low starting cell number undergoing the ...

Application of cDNA arrays to monitor mRNA profiles in single preimplantation mouse embryos.

Array technology is a widely used tool for gene expression profiling in various biological systems. However, the application of this method to mammalian preimplantation embryos is limited by the small amount of mRNA that can be extracted from a single embryo, which is not sufficient for array analysis. Here we report a protocolfor the rapid global amplification of embryonic mRNA that permits th...

Expression of interleukin-1 system mRNA in single blastomeres from human preimplantation embryos.

Gathering knowledge about the molecular events during preimplantation development is one of the most important challenges in in-vitro fertilization (IVF). The interleukin-1 (IL-1) system has been shown to be intimately involved in embryonic implantation. The aim of our study was to detect the major components of the IL-1 system in single blastomeres from human preimplantation embryos and to rel...
