WebDifferential expression (DE) analysis is a necessary step in the analysis of single-cell RNA sequencing (scRNA-seq) and spatially resolved transcriptomics (SRT) data. Unlike traditional bulk RNA-seq, DE analysis for scRNA-seq or SRT data has unique characteristics that may contribute to the difficulty of detecting DE genes. WebJan 1, 2024 · Lun and Marioni proposed to aggregate/sum counts from all cells in each batch into one pseudo-bulk sample [24].

Differential Expression Analysis for Single-cell RNA-seq

WebNov 10, 2024 · As differential expression analysis is done on the whole set of genes, the resulting pvalues will have a distribution corresponding to the combination of both histograms. Most of the p-values are uniformly distributed between 0 and 1 but there is a spike to the left close to zero, due to those p-values for which \(H_0\) is false. WebPseudo-bulk functional analysis When cell lineage is clear (there are clear cell identity clusters), it might be beneficial to perform functional analyses at the pseudo-bulk level instead of the single-cell. By doing so, we recover lowly expressed genes that before …
