title: mRNA-sequencing whole transcriptome analysis of a single cell on the SOLiD system.
abstract: We have developed a sequencing-based gene expression profiling assay at single-cell resolution by combining a modified single-cell whole transcriptome amplification method with the next generation sequencing technique, the SOLiD system. Using this assay, we have shown that blastomeres in a four-cell stage embryo have similar gene expression, which is compatible with the fact that they have similar developmental potential. We proved that compared with cDNA microarray technique, our single-cell cDNA SOLiD sequencing assay can detect expression of thousands of more genes. Moreover, for the genes detected by microarray and SOLiD sequencing, our assay detected new transcript variants for a large proportion of them, which confirms unambiguously at single-cell resolution that the transcriptome complexity is higher than expected traditionally. Finally, by using our assay to Dicer knockout (KO) and Ago2 KO oocytes, we showed that a significant amount of transposons were up-regulated abnormally in Dicer/Ago2 KO mature oocytes compared with wild-type controls.
