A contribution to studies on the mechanism of lymphocyte-induced angiogenesis: human peripheral blood mononuclear leucocytes with highest angiogenic activity.

Using the lymphocyte-induced angiogenesis test a comparison of angiogenic activity of some mononuclear cell fractions was performed. It is shown that the highest angiogenic activity was expressed by cells bearing both the receptor for the Fe portion of IgG and a CD4 surface antigen.
