Due to our aging population and the prevalence of neovascular age-related macular degeneration (AMD), there is great need for a reproducible model for translational research. On March 8, 2016, InsideScientific hosted a webinar sponsored by Phoenix Research Labs on the development of a Choroidal Neovascularization (CNV) model of AMD by speaker Yan Gong, PhD and a team at Harvard Medical School. Dr. Gong describes the process for achieving choroidal neovascularization in mice in detail, from proper mouse selection and image-guided optical coherence tomography to RNA and protein extraction and data analysis.

Dr. Gong also discusses how to achieve consistent lesions using image-guided laser, the use of Fundus Fluorescein Angiography to determine leakage, and a set of guidelines to optimize the process using the Phoenix Micron IV platform.

This webinar is an excellent resource for any researcher studying AMD that has considered using the CNV model in their lab.
