Injection of bone marrow-derived conditioned medium for angiogenesis

Abstract

Methods are provided for promoting formation of collateral blood supply at an ischemic site in tissue by culturing early attaching cells derived from growth of bone marrow aspirate in vitro, collecting early attaching cells produced by the bone marrow culture and injecting conditioned medium produced by culture of the early attaching cells into an ischemic site in heart or limb. The preferred early attaching cells for use in the invention methods are marrow-derived stromal cells. Any donor's bone marrow can be used in preparation of the conditioned medium. Optionally, the early attaching cells can be transfected with an angiogenesis promoting transgene encoding hypoxia inducing factor 1 alpha, a fibroblast growth factor and/or a nitric oxide synthase. Conditioned media containing angiogenic cytokines produced such cells are also provided for injection into tissue, such as heart or peripheral limb muscle, requiring formation of collateral blood supply.
