This PDF file includes:

  • Materials and Methods
  • Fig. S1. ROCK inhibition with Fasudil and Y-27632 impairs ECM integrity.
  • Fig. S2. The CDK1-FRET biosensor distinguishes changes in CDK1 activity and is a surrogate for cell cycle arrest.
  • Fig. S3. Priming with Fasudil disrupts ECM remodeling, inhibits ROCK signaling, and improves Gem/Abraxane efficacy in vivo.
  • Fig. S4. Priming with Fasudil influences liver vasculature, cell attachment to CDMs, response to chemotherapy, and remodeling of the ECM.
  • Fig. S5. Priming with Fasudil results in decreased SRC activity and defects in mitosis.
  • Fig. S6. High ECM TKCC5 patient model responds to priming strategies in a 3D patient-personalized organotypic matrix.
  • Fig. S7. Low ECM TKCC2 patient model does not respond to priming strategies in a 3D patient-personalized organotypic matrix.
  • Fig. S8. TKCC5 orthotopic tumors respond to priming, and SHG does not predict survival.
  • Fig. S9. Priming with Fasudil uncouples PC progression.
  • Table S1. List of P values.
  • Table S2. Details of antibodies used for the study.
  • Legends for movies S1 to S9
