Boxplot showing the spatial correlation between different cell types and Fbp1 + AMs of nine lung slides at d14. Data are represented as mean +/- SEM ( n = 9 slides per timepoint). Center line, median; box bounds, first and third quartiles; whiskers, 1.5 times the interquartile range. Kruskal–Wallis test was performed to calculate the P value across different groups. Pearson correlation was performed to calculate the P value of all spots within each slide. Black dots: P < 0.05; gray dots: P >= 0.05. Red dotted line represents the correlation value of 0.
