(G) Stacked bar plot (Marimekko chart) color-coded for the relative contribution of cells derived from SPF (green) and GF (yellow) mice. Ranges of p-values are provided for significantly enriched condition per cluster, based on hypergeometric tests. Benjamini-Hochberg correction was applied to correct for multiple testing (*P < 0.05; **P < 0.01; ***P < 0.001).
