Cell-based therapy for the pulmonary system
Cell based therapy comprises administration to the lung by injection into the blood system of viable, mammalian cells effective for alleviating or inhibiting pulmonary disorders. The cells may express a therapeutic transgene or the cells may be therapeutic in their own right by inducing regenerative effects.
1. A process of alleviating a state selected from the group consisting of lung inflammation, septal edema, alveolar inflammation, and endothelial inflammation, in a mammalian patient, comprising administering to the lung by injection into the pulmonary circulation of the patient of syngeneic or allogeneic or autologous mesenchymal stem cells, said cells having been transformed in vitro to express angiopoeitin; wherein the administration results in alleviation of the state.
2. The process of claim 1 wherein the state is a result of, or caused by, acute lung injury.
3. The process of claim 1 wherein the state is associated with acute respiratory distress syndrome.
4. The process of claim 1 wherein the cells are allogenic.
5. The process of claim 1 wherein the cells are autologous.
