Lymphangiography of the mouse tail

Area of Science:

• Oncology
• Vascular Biology
• Surgical Techniques

Background:

• The lymphatic system is a critical pathway for cancer cell spread (metastasis).
• Understanding lymphatic vessel dynamics is key to developing anti-metastasis therapies.
• Current methods for studying lymphatic function in vivo can be limited.

Purpose of the Study:

• To describe a novel method for assessing lymphatic microvessel structure and function in a mouse tail model.
• To enable the monitoring of lymphatic system changes in the presence of a tumor.
• To provide a protocol for tumor cell injection and subsequent microlymphangiography.

Main Methods:

• Adaptation of lymphangiography for use in the mouse tail model.
• Injection of a high-molecular-weight, fluorescently labeled tracer into the tail's interstitial space.
• Tumor cell implantation in the mouse tail to study peritumoral lymphatic changes.
• Microlymphangiography to visualize the lymphatic network.

Main Results:

• The described technique allows for the visualization of lymphatic microvessels in the mouse tail.
• The method enables the monitoring of lymphatic structure and function at the tumor periphery.
• The protocol facilitates the study of cancer cell interaction with the lymphatic system.

Conclusions:

• Microlymphangiography in the mouse tail is a viable method for studying lymphatic metastasis.
• This model provides a platform for investigating tumor-induced changes in lymphatic vessels.
• The described protocol can advance research into cancer spread and therapeutic strategies.
