Correlation analysis between gut microbial phyla, alpha-diversity, total bacterial abundance, barrier integrity, and gene expression. Heatmap (correlation matrix) of Pearson correlation coefficients (R) between the relative abundance (%) of bacterial phyla, small intestinal gene expression of tight junction proteins and intestinal epithelial cells (IECs) marker, alpha-diversity metrics, gut barrier integrity (%), 16S rRNA total abundance, cecal IgA and goblet cells during the postnatal development period in mice. (∗p ≤ 0.05, ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.001 and ∗∗∗∗p ≤ 0.0001).
