CD44v6 Dependence of Premetastatic Niche Preparation by Exosomes
The metastasizing capacity of the rat pancreatic adenocarcinoma BSp73ASML (ASMLwt) is strikingly reduced by a knockdown of CD44v4-v7 (ASMLkd). We used this model to analyze the role of the CD44 variant isoform (CD44v) in (pre)metastatic niche formation. Intrafootpad injections of ASMLwt-, but not AS...

description | The metastasizing capacity of the rat pancreatic adenocarcinoma BSp73ASML (ASMLwt) is strikingly reduced by a knockdown of CD44v4-v7 (ASMLkd). We used this model to analyze the role of the CD44 variant isoform (CD44v) in (pre)metastatic niche formation. Intrafootpad injections of ASMLwt-, but not ASMLkd-conditioned medium (CM), strongly promote settlement of ASMLkd cells in lymph nodes and lung. Fractionation of CM revealed a contribution by a soluble matrix and exosomes, where the CD44v6-containing ASMLwt-soluble fraction can complement ASMLkd-exosomes, but not vice versa. This implies that exosomes are the final actors, are CD44v-independent, but require a soluble matrix, which depends on CD44v. Analyzing the composition revealed that only the ASMLwt-matrix contains c-Met and urokinase-type plasminogen activator receptor. In vitro, mostly ASMLwt-exosomes promote proliferation and induce gene expression in metastatic organ cells. However, in vivo corresponding changes in the (pre) metastatic organ are only observed when both, exosomes plus the soluble matrix, are provided. Thus, neither CD44v nor exosomes alone suffice for (pre)metastatic niche formation. Instead, CD44v suffices for assembling a soluble matrix, which allows exosomes, independent of their origin from poorly or highly metastatic cells, to modulate (pre) metastatic organ cells for tumor cell embedding and growth. |
