This video demonstrates the surgical isolation procedure of the inguinal draining lymph node from a mouse model. Incision of the abdominal region provides access to the inguinal lymph node, which is surgically harvested. The harvested translucent inguinal lymph node can be used for immunological studies.

This video demonstrates a dissection technique to harvest popliteal draining lymph nodes from the mouse hind legs. Lymph nodes play a critical role in bridging innate and adaptive immunity, and harvesting intact lymph nodes — with a preserved tissue structure and cellular viability — can help study local and systemic immune responses.

Fluid Connective Tissues: Blood and Lymph

Blood and lymph are fluid connective tissues. They contain cells, also known as formed elements, circulating in a liquid extracellular matrix, the plasma. The formed elements are derived from hematopoietic stem cells in the bone marrow. Blood and lymph connect all vital parts and carry nutrients, oxygen, and other essential molecules like antibodies. Blood The blood flows through blood vessels— arteries, capillaries, and veins. Blood plasma is primarily made of proteins, solutes, and water.

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The lymphatic system has two main functions: to return extracellular fluid back to the venous circulation and to expose antigenic substances to the immune system. As the collected fluid passes through lymphatic channels on its way back to the systemic circulation, it encounters multiple nodes consisting of highly concentrated clusters of...
FAQs
Preserving the collected material allows investigators to examine multiple aspects of lymph transport at once. Soluble factors can indicate immune signaling, while leukocytes, antigens, pathogens, and microbial products provide information about transported cellular and infectious material. Maintaining these components under controlled collection conditions helps connect sample composition with activity occurring in tissues and draining lymph nodes.
Analysis can show which immune materials are moving from tissues toward lymph nodes and how that movement relates to host responses. Samples may contain leukocytes, cytokines, antibodies, antigens, pathogens, or microbial products. Examining these components together helps researchers assess immune activity and identify signals associated with inflammation or infection rather than studying lymphatic transport alone.
Lymph connects affected tissues with draining lymph nodes, so collected fluid can contain transported signals before or during the development of a broader immune response. Investigators can examine cytokines, antigens, pathogens, and microbial products in the sample to identify early changes associated with infection. This supports analysis of how local events become detectable in lymphoid tissues.
Collection requires careful access to a lymphatic vessel or draining tissue, commonly through cannulation or drainage, while maintaining controlled conditions. The goal is to obtain lymph without losing the immune cells, soluble factors, antigens, or transported infectious materials relevant to analysis. Careful handling therefore supports more informative measurements of both fluid transport and immune activity.
Harvested lymph provides a way to examine immune materials moving from tissues during inflammation or after vaccination. Researchers can analyze transported leukocytes, cytokines, antibodies, and antigens to assess local immune activity and communication with draining lymph nodes. These measurements help connect tissue events with downstream immune responses and can clarify how lymphatic transport contributes to each process.
The collected fluid can be evaluated for both its transported contents and the relationship between those contents and lymphatic movement. Finding immune cells, signaling molecules, antigens, or infectious materials in lymph helps investigators assess how material travels from tissues to lymph nodes. This makes the approach useful for linking fluid transport with immunological and infection-related outcomes.
