Angiogenesis Model 

The study and development of anti-angiogenic therapies depends on reliable and reproducible stimulation models of neovascular response. Charles River Discovery Services has several experimental techniques that allow an effective examination of short-term neovascularization and angiogenic response to bFGF, VEGF or other angiogenic stimuli.

Corneal Micropocket Assay

  • Hydron pellet prepared with growth factors chosen for specific study requirements
  • Surgical implantation of pellet into a corneal micropocket
  • Corneal neovascularization measured using slit-lamp microscope
  • Short-term study with rapid turnaround times

bFGF100VEGF

                               bFGF100                                       VEGF

bFGF and VEGF Day 6
bFGF and VEGF Day 6


In vivo
screens using angiogenic-dependent tumor growth.

  • Bevacizumab can be used as a positive control.

 

Metronomic dosing (Browder, 2000; Cancer Research 60:1878)

  • Long-term, low-level dosing of cytotoxics or other agents of interest to inhibit growth and development of vascular endothelium while avoiding whole-animal toxicity
  • Metronomic dose determination for use in efficacy study
  • Studies can last up till 90 days.
