MMP11 and posterior cortical atrophy: We further analyzed the communication of MMP11(+) F01 with other cell types in the microenvironment of PCa and showed that MMP11(+) F01 not only communicated more intensively with other cell types compared to MMP11(-) fibroblasts but also affected T cells, NK/CTL, and myeloid cells through a greater number of TGFβ-associated receptor-ligand pairs (Figures 8A-C).
