Compositions and methods for treating organ dysfunction
View Patent ↗A method of retarding cellular senescence comprising (i) providing an extracellular matrix (ECM) composition comprising ECM from an adolescent tissue source, the ECM comprising an exogenously added cytokine, and (ii) administering ECM composition to an organ with cells exhibiting cellular senescence, wherein, the cytokine interacts with at least one molecule in the ECM composition and modulates ROS production of the cells, whereby, the cellular senescence is abated.

an extracellular matrix (ECM) composition comprising ECM from a mammalian tissue source comprising small intestine submucosa, said ECM comprising endogenous proteoglycans, transforming growth factors-β (TGF-β), fibroblast growth factors-2 (FGF-2) and vascular endothelial growth factor (VEGF), said ECM further comprising an exogenously added cytokine, said cytokine comprising at least 0.1% by weight of said composition,
said cytokine being linked to said ECM, wherein, when said composition is administered to biological tissue, said cytokine interacts with at least one molecule in said ECM composition, wherein said ECM composition modulates ROS production and, thereby, telomere activity.
2. The composition of claim 1 , wherein said cytokine is selected from the group consisting of interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-6 (IL-6), interleukin-9 (IL-9), interleukin-10 (IL-10), interleukin-13 (IL-13), interleukin 31 (IL-31), and interleukin-33 (IL-33).
3. The composition of claim 1 , wherein said mammalian tissue source comprises an adolescent tissue source.
4. The composition of claim 1 , wherein said ECM composition further comprises an exogenously added growth factor selected from the group consisting of a transforming growth factor-alpha (TGF-α), transforming growth factor-beta (TGF-β), fibroblast growth factor-2 (FGF-2), basic fibroblast growth factor (bFGF), vascular epithelial growth factor (VEGF) and hepatocyte growth factor (HGF).
5. The composition of claim 1 , wherein said ECM composition further comprises an exogenously added HMG-CoA reductase inhibitor selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin.
6. A composition for treating mammalian organ dysfunction, comprising:
an extracellular matrix (ECM) composition comprising ECM from a mammalian tissue source comprising mesothelial tissue, said ECM comprising endogenous proteoglycans, transforming growth factors-β (TGF-β), fibroblast growth factors-2 (FGF-2) and vascular endothelial growth factor (VEGF), said ECM further comprising an exogenously added cytokine, said cytokine comprising at least 0.1% by weight of said composition,
said cytokine being linked to said ECM, wherein, when said composition is administered to biological tissue, said cytokine interacts with at least one molecule in said ECM composition, wherein said ECM composition modulates ROS production and, thereby, telomere activity.
7. The composition of claim 6 , wherein said cytokine is selected from the group consisting of interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-6 (IL-6), interleukin-9 (IL-9), interleukin-10 (IL-10), interleukin-13 (IL-13), interleukin 31 (IL-31), and interleukin-33 (IL-33).
8. The composition of claim 6 , wherein said mammalian tissue source comprises an adolescent tissue source.
9. The composition of claim 6 , wherein said ECM composition further comprises an exogenously added growth factor selected from the group consisting of a transforming growth factor-alpha (TGF-α), transforming growth factor-beta (TGF-β), fibroblast growth factor-2 (FGF-2), basic fibroblast growth factor (bFGF), vascular epithelial growth factor (VEGF) and hepatocyte growth factor (HGF).
10. The composition of claim 6 , wherein said ECM composition further comprises an exogenously added HMG-CoA reductase inhibitor selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin.
11. A method of retarding cellular senescence of an organ, comprising the steps of:
providing an extracellular matrix (ECM) composition, said ECM composition comprising ECM from an adolescent tissue source, said ECM comprising endogenous proteoglycans, transforming growth factors-β (TGF-β), fibroblast growth factors-2 (FGF-2) and vascular endothelial growth factor (VEGF), said ECM further comprising an exogenously added cytokine, said cytokine comprising at least 0.1% by weight of said composition; and
administering said ECM composition to an organ with cells exhibiting cellular senescence, wherein, said cytokine interacts with at least one molecule in said ECM composition, wherein said ECM composition modulates ROS production of said cells and, wherein, said cellular senescence is abated.
12. The method of claim 11 , wherein said tissue source comprises small intestine submucosa.
13. The method of claim 11 , wherein said tissue source comprises mesothelial tissue.
14. The method of claim 11 , wherein said cytokine is selected from the group consisting of interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-6 (IL-6), interleukin-9 (IL-9), interleukin-10 (IL-10), interleukin-13 (IL-13), interleukin 31 (IL-31), and interleukin-33 (IL-33).
15. The method of claim 11 , wherein said ECM composition further comprises an exogenously added growth factor selected from the group consisting of a transforming growth factor-alpha (TGF-α), transforming growth factor-beta (TGF-β), fibroblast growth factor-2 (FGF-2), basic fibroblast growth factor (bFGF), vascular epithelial growth factor (VEGF) and hepatocyte growth factor (HGF).
16. The method of claim 11 , wherein said ECM composition further comprises an exogenously added HMG-CoA reductase inhibitor selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin.
