Possibility of Using Mesenchymal Stromal Cells to Restore Lymph Flow in Experimental Phlebothrombosis

Аннотация

The possibility of formation of lymphatic vessels after introduction of autologous bone marrow-derived multipotent mesenchymal stromal cells transfected with GFP gene into thrombosed femoral vein was studied by fluorescent microscopy. Vascular thrombosis caused by ligation of the great vein with subsequent injection of thrombin solution was accompanied by blockade of regional lymph flow. The cells injected into thrombosed vein directly participate in the formation of new lymphatic vessels in the paravasal tissue surrounding the vein, its tissue region, and around regional lymph nodes. This is seen from bright specific fluorescence of individual cells in the walls of lymphatic vessels and all vascular layers and valves in UV light.
