COL15A1 and IGF2 were upregulated in FAPs‐high versus FAPs‐low region in TB pig and had higher expression in MuSCs of TB than that of Duroc pig, indicating that MuSCs‐derived COL15A1 and IGF2 were connected with the distribution of FAPs in TB pig (Figure S7A and Table S8). This evidence concerns the gene COL15A1 and tuberculosis.
