Treatment of vasculopathy with prostacyclin and mesenchymal stem cells
Provided are methods for treating or preventing vasculopathy in a subject in need thereof, comprising administering to the subject a prostacyclin and a mesenchymal stem cell (MSC) or a MSC-conditioned culture medium or administering to the subject a MSC or a MSC-conditioned culture medium that has treated with prostacyclin. Pharmaceutical compositions suitable for such treatments are also provided.
1. A method for treating or preventing vasculopathy in a subject in need thereof, comprising administering to the subject a prostacyclin and a composition comprising (i) a part of a culture medium that has been in contact with a mesenchymal stem cell (MSC) and contains one or more components of the MSC, wherein the component(s) of the MSC comprises a microRNA, a messenger RNA, a non-coding RNA, a mitochondria, a growth factor, or combinations thereof, or (ii) an exosome derived from the MSC, wherein the vasculopathy is selected from the group consisting of pulmonary arterial hypertension (PAH), peripheral vascular disease (PVD), critical limb ischemia (CLI), coronary artery disease and diabetic vasculopathy.
2. The method of claim 1 , wherein the prostacyclin and the composition are administered concurrently.
3. The method of claim 1 , wherein the prostacyclin and the composition are administered separately.
4. The method of claim 1 , further comprising, prior to the administration, contacting the part of the culture medium with a prostacyclin.
5. The method of claim 1 , wherein the component(s) of the MSC is selected from the group consisting of an exosome, a microvesicle, a microRNA, a messenger RNA, a non-coding RNA, a mitochondria, a growth factor, and combinations thereof.
6. The method of claim 1 , wherein the prostacyclin is selected from the group consisting of epoprostenol, treprostinil, beraprost, ilprost, a PGI 2 receptor agonist, and pharmaceutically acceptable salts thereof.
7. The method of claim 6 , wherein the prostacyclin is treprostinil or a pharmaceutically acceptable salt or ester thereof.
8. The method of claim 1 , wherein the MSC is a mesenchymal precursor cell (MPC).
9. The method of claim 1 , wherein the MSC is obtained from bone marrow.
10. The method of claim 1 , wherein an exosome derived from the MSC is administered to the subject.
