Expression profiling of cell intrinsic regulators in the process of differentiation of human iPSCs into retinal lineages

2018
PMCID: 5948821
PMID: 29751772
DOI: 10.1186/s13287-018-0848-7

[…] (http://www.bioconductor.org). the raw intensity data were background corrected, log2 transformed and quantile normalized using the robust multi-array average (rma) algorithm implemented by the affy package []. the differentially expressed genes (degs) were further identified using the limma package []. the probe sets that demonstrated benjamini–hochberg adjusted p < 0.01 and log2 […]
