Murine Tail Lymphedema Model: An In Vivo Technique to Generate Sustained Lymphedema in Murine Tail

Abstract

Source: Hassanein, A. H. et al., A Murine Tail Lymphedema Model. J. Vis. Exp. (2021).

This video describes an in vivo technique to generate murine tail lymphedema, an abnormal fluid accumulation in the interstitial tissue space leading to swelling in the tail. The model is applied to study mechanisms and therapy for lymphedema.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Surgical Disruption of Mouse Tail Lymphatics Use eight week-old C57BL/6 mice of equal gender distribution. Place a mouse under general anesthesia in an induction chamber with 3-4% isoflurane in 100% oxygen followed by maintenance sedation at 1-3% during the procedure. Administer 0.5 mg/kg sustained-r…
