摘要：
Disclosed are compositions with sustained-release carriers associated with at least two different types of growth factors and methods of fabrication and treatments thereof. In some embodiments, simultaneous release of the growth factors may be preferred while in other embodiments, sequential release of the growth factors may be preferred. Application of at least two growth factors to an injury site, e.g., compromised cardiac tissue caused by, for example, myocardial infarction or ischemic heart failure, may better mimic and induce the complex growth factor signaling pathways necessary to improve cardiac function. When applied to a patient after a myocardial infarction or ischemic heart failure, multiple growth factors within a sustained-release carrier platform or platforms may cause a synergistic effect on injected cells intending to alleviate left ventricle remodeling. Methods of treatment include percutaneous, sub-xiphoid, and open chest methods using catheters and/or syringes.
