Study design and transcriptome in six pig immune tissues. A We collected six kinds of immune tissues from one-month-old Landrace piglets, and analyzed the specific expression and co-expression patterns among the immune tissues to construct a comprehensive immune transcriptome of Landrace pigs; Then we also collected PBMCs of 4-month-old and 7-month-old pigs to analyze the immune dynamics of PBMCs combined with three time points, and collected PBMCs of local breed Songliao Black pig to analyze the immune differences among different breeds. B PCA analysis of six immune tissue samples of Landrace piglets based on gene expression levels. C Unsupervised clustering of the samples. D Pearson correlation (heatmap) of transcriptome profiles across six immune tissues. E Histogram of the number of tissue-specific gene expression obtained from six immune tissues (τ > 0.8)
