Intracardiac Delivery of Viral Vectors: A Technique to Inject Viral Vectors Intracardially to Study Pancreatic Metastasis in Murine Model
Overview
This video describes the protocol for intracardiac injection of retroviruses into the transgenic mouse to ensure gene transfer into proliferating pancreatic β premalignant lesions. This method can also help in assessing the functions of candidate genes in tumor metastasis.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the jove veterinary review board.
1. Intracardiac injection:
Hemizygous RIP-Tag mice, not homozygous mice, are used in this study. Hemizygous RIP-Tag mice develop pancreatic neuroendocrine tumors around 10~12 weeks of age, while homozygous mice have a shorter tumor latency. Because cell proliferation is requi.......
Representative Results
Figure 1: Placement of intracardiac injection. Anatomical landmarks are shown with horizontal dashed lines on the sternum (outlined in white). On the mouse's skin, the sternal notch and xiphoid process serve as landmarks, and the needle is inserted 1 mm away from the mid-sternum and slightly left (anatomical) of the sternum.
