Аннотация
Hemorrhagic changes after subcutaneous injection of autologous bone marrow multipotent mesenchymal cells with transfected GFP gene and additionally stained cell membranes to WAG rats in the projection of ligated femoral vein were studied by fluorescent microscopy. Hemorrhages in tissues with experimental acute local venous occlusion were caused by a combination of venous hypertension with inflammation around the foreign body — the ligature used for ligation of the vein. Fibrin found in tissues together with erythrocytes in the hemorrhages could stimulate the formation of granulations and new vessels instead of damaged or thrombosed ones. Multipotent mesenchymal stromal cells and their detritus getting into the regional lymph nodes initiated immune reactions morphologically confirmed by stubborn hypertrophy and hyperplasia of the lymphoid nodules, hemorrhages, and manifest diapedesis of erythrocytes to the organ parenchyma and sinus system.
