title: Angiogenesis after transplantation of auto- and allogenic cells.
abstract: Neoangiogenesis after transplantation of auto- and allogenic mononuclears and multipotent stromal cells from the bone marrow was studied on the model of inflammatory angiogenesis. Transplanted auto- and allogenic cells stimulate the formation of new blood vessels in the granulation tissue, this manifesting in an increase in the quantity and volume density of blood vessels. The most pronounced angiogenesis was observed after transplantation of allogenic mononuclears and multipotent stromal cells. It was associated with intense inflammatory infiltration, with less numerous and mature collagen fibers in the granulation tissue. Injection of allogenic cells led to stimulation and chronization of inflammation, infiltration with inflammatory and poorly differentiated cells, and more pronounced and lasting angiogenesis. However, neither auto-, nor allogenic transplanted labeled cells were detected in the walls of new blood vessels. Hence, it seems that bone marrow mononuclears and multipotent stromal cells stimulated angiogenesis mainly at the expense of production of angiogenic factors, and after transplantation of allogenic cells also by stimulating the inflammation.
