To investigate whether LGMN is required for chemokine-triggered macrophage migration, Raw264.7 and THP1 macrophages were placed in Transwell inserts with or without the stimulation of a known chemokine, C-C motif chemokine ligand 2 (CCL2), or GBM cell conditioned medium (CM). This evidence concerns the gene CCL2 and glioblastoma.
