As depicted in Figure S9, peritoneal CAFs were isolated from tumor-bearing WT or TgMISIIR-TAg-Low mice by negative selection using the CD45+ column, and recovered cells consisting of over 88% of CD49e+ FAP+ CAFs were injected i.p. into WT mice 1 day after tumor inoculation, followed by OV-CXCR4-A treatment 9 days later. Here, ITGA5 is linked to neoplasm.
