The topographical organization of collagen within the tumor microenvironment has
been implicated in modulating cancer cell migration and independently predicts
progression to metastasis. Here, we show that collagen matrices with small pores
and short fibers, but not Matrigel, trigger a conserved transcriptional response
and subsequent motility switch in cancer cells resulting in the formation of
multicellular network structures. The response is not mediated by hypoxia, matrix
stiffness, or bulk matrix density, but rather by matrix architecture-induced
?1-integrin upregulation. The transcriptional module associated with network
formation is enriched for migration and vasculogenesis-associated genes that
predict survival in patient data across nine distinct tumor types. Evidence of
this gene module at the protein level is found in patient tumor slices displaying
a vasculogenic mimicry (VM) phenotype. Our findings link a collagen-induced
migration program to VM and suggest that this process may be broadly relevant to
metastatic progression in solid human cancers.
