BM-MSCs promote PC-3 Migration, Invasion and Adhesion. PC-3 (A) migration toward BM-MSCs in co-culture (****p < 0.0001), (B) migration toward BM-MSC CM (****p < 0.0001), (C) invasion toward BM-MSC CM (****p < 0.001), (D) adhesion to BM-MSC CM (*****p < 0.0001), (E) cell count after 72 h culture in BM-MSC CM (n.s.). Number of migrated and invaded cells reported are mean ± SD of 5 representative fields on the membrane. Proportion adherence reported is mean ± SD (n = 3) of the ratio of adherent to input cells as determined by cell viability (MTS) assay. Cell count reported is mean ± SD (n = 3) of cell viability (MTS). SFM: serum free media, MSC CM: BM-MSC conditioned media.
