CCR7 knockout inhibits M2 macrophage polarization. a and b Transwell assay shows the invasion and migration ability of PCI-37B and PCI-4B cells between different experimental groups. c and d Wound healing assay shows the migration ability of PCI-37B and PCI-4B cells between different experimental groups. e and f CCK8 assay shows the proliferation ability of PCI-37B and PCI-4B cells between different experimental groups.
