Continuous Drug Infusion System in Mouse Model: A Surgical Procedure to Implant Micro-osmotic Pump Infusion System in the Mouse Brain for Continuous Drug Delivery
Overview
In this video, we demonstrate the assembly of a micro-osmotic pump brain infusion system followed by its surgical implantation in the mouse skull. This system enables continuous delivery of potential drugs and facilitates the study of their effects on the brain and brain tissue.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
1. Preparation of Micro-Osmotic Pump Infusion Systems
NOTE: Prepare the pump, artificial cerebrospinal fluid (aCSF) buffer, and drug (Met-CCL5/RANTES protein solution (10 ng/mL in aCSF)) under sterile conditions using buffers filtered with 0.2 µm filters and conduct all the procedures un.......
