Description

DESCRIPTION (provided by applicant): Cardiopoietic cell therapy significantly improved left ventricular function, blunted pathological remodeling, and functional outcomes in animal models and Phase I/II clinical trial of heart failure patients. There is ongoing Phase III trial. In this therapeutic approach, bone marrow-derived mesenchymal stem cells are engaged into cardiac stem cells by exposing to a cardiogenic cocktail of growth factors, including activin A, transforming growth factor-b1, and bone morphogenetic protein-4, which is the single largest cost component of clinical manufacturing. These cytokines all belong to the TGF-b superfamily, which are critical for cardiopoietic stem cell expansion and differentiation. However, due to the complex post-proteolytic modifications and poor solubility at neutral pH, yield from all the curren manufacturing process is very low, and as a result bulk volume is uneconomical and not readily available. Currently, commercial products are transiently produced in no
