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
 
bFGF100 VEGF
 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.

Angiogenesis Models | Charles River Discovery Services
Charles River offers angiogenesis models using metronomic dosing. By examining corneal neovascularization, angiogenic efficacy evaluation can be determined via the corneal micropocket assay and in vitro/in vivo screening in angiogenic tumor cell lines.
