Overall Desgin | 6 single human HepG2 cell line cells were sequenced using the newly developed scTrio-seq, other 2 HepG2 cells were sequenced using scRNA-seq and other 2 HepG2 cells were sequenced using scRRBS as technique control. 6 single mouse embryonic stem cells (mESCs) were sequenced using the newly developted scTrio-seq. Meanwhile, two scRNA-seq and two scRRBS were also completed using two mESCs separately. 26 single cells from hepatocellular carcinoma were sequenced using scTrio-seq to analyze the regulation relations between three omics of cancer cells. |
Summary | Single cell genome, DNA methylome, and transcriptome sequencing has been achieved separately. However, to analyze the regulation of RNA expression by genetic and epigenetic factors within an individual cell, it is necessary to analyze these omics simultaneously from the same single cell. Here we developed a single cell triple omics sequencing technique- scTrio-seq, to analyze the genome, DNA methylome, and transcriptome concurrently of a mammalian cell. |
Experimental Protocol | The RNA and DNA of each single cell were separated and extracted by Trio-seq.; For RNA seq and genome DNA seq data, we constructed the sequencing libraries using NEBNext Ultra DNA Library Prep Kit for Illumina (NEB #7370L). RRBS libraries were constructed using RRBS protocol as described in 2013 (Guo et al. 2013)

Data processing | Illumina CASAVA version 1.8 were used to the basecalling.; Adapter sequence and low-quality sequences were trimmed.; For RNA seq data, TopHat (version 2.0.10) were used for sequence alignment to human hg19 genome. Gene expression level (FPKM) were calculated using Cufflinks (version 2.1.1).; For RRBS data, Bismark were used for sequence alignment to human (hg19) genome, and metlevel of each CpG site were calculated manually.; For gDNA seq data, bwa were used for sequence alignment to the human (hg19) genome, and the depth for each 10M window were calculated by summing the sequencing depth of all the positions in each window.; Genome_build: hg19 Illumina CASAVA version 1.8 were used to the basecalling.; Adapter sequence and low-quality sequences were trimmed.; For RNA seq data, TopHat (version 2.0.10) were used for sequence alignment to mouse mm9 genome.
