Figure Lengend Snippet: (A) Schematic of evaluating differentially expressed genes (DEGs) using the overlap between bulk RNA-seq and scRNA-seq – also shown in . Using the pairs of cell lines in the sc_10x_5cl dataset, ENCODE_fluidigm_5cl dataset, and pairs of cell types in the bone marrow tissue from the HCA_10x_tissue dataset, we show heatmaps of proportion of overlap between bulk and single-cell DEGs identified using (B, D, F) MAST and (C, E, G) Wilcoxon-rank-sum test (abbreviated as Wilcoxon) for differential expression, respectively. (H) Schematic of a null differential expression analysis by randomly partitioning cells from the same cell type into two groups – also shown in . Using the 293T cells from the 10x_293t_jurkat dataset, the GM12878 cells from the ENCODE_fluidigm_5cl dataset, and bone marrow cells from the HCA_10x_tissue dataset, the number of false positive DEGs identified using (I, K, M) MAST and (J, L, N) Wilcoxon, respectively. The x-axis in Figures (I-N) describe the number of cells in each group (e.g. 10 sampled cells in group 1 and 10 sampled cells in group 2) when applying a method to identify differentially expressed genes. White areas with black outline indicate that the imputation methods did not return output after 72 hours and areas with grey outline indicate that either MAST or Wilcoxon failed to return results.
Article Snippet: The test data include 10x Genomics UMI-based scRNA-seq data for 293T and Jurkat cell lines ( 10x_293T_jurkat ) and Fluidigm C1 plate-based scRNA-seq read count data for five ENCODE cell lines ( ENCODE_fluidigm_5cl ).
