What effect might an injection of RGD peptide have on tumor cells moving through the blood/lymph system?

#SCPH28 | Zoology
  1. block cell attachment to new tissue and therefore prevent metastasis

  2. encourage clumping of cancer cells for removal by the immune system

  3. promote tumor cell binding to platelets and potentially lead to a fatal clot

  4. block integrin-mediated cell cycle progression
