Animal Surgery

Technical support and experiments to generate rodent models of neurological disorders Read More


The overall objective of the Animal Surgery Core (ASC) is to assist translation of scientific discoveries to rodent models and to facilitate development of new therapeutic strategies for nervous system disorders. The ASC provides access to core equipment and facilities, and expertise for surgery or protocol development. In addition, specific surgical and genetic models of disease will be made available to the Washington University community to accelerate investigation in disorder-related neuroscience.

Additionally, equipment in the facility is open to Hope Center investigators who complete appropriate training. Animal Studies Committee approval is required.

Acknowledging the Core

The Animal Surgery Core has been supported by grants as well as the Hope Center for Neurological Disorders. Publications that include data from core use should acknowledge as appropriate (suggested language below).  Acknowledgements are crucial in tracking success of the core and obtaining future funding, and are required by the NIH Public Access Policy.

If your core use was after August 2013, then the suggested language is the following.

“This work was supported by the Hope Center Animal Surgery Core at Washington University School of Medicine.”

If your core use was before August 2013, then the suggested language should reference the Neuroscience Blueprint award.

“This work was supported by the Hope Center Animal Surgery Core and a P30 Neuroscience Blueprint Interdisciplinary Center Core award to Washington University (P30 NS057105).”


We always strive to improve services and resources offered by the Hope Center Cores.  To provide feedback, see contact information below.
