Construction of a myocardial patch with mesenchymal stem cells and poly(CL-co-TOSUO)/collagen scaffolds for myocardial infarction repair by coaxial electrospinning

PCT/collagen core shell nanofibers with elasticity similar to a natural myocardium were developed as scaffolds of a MSC cardiac patch, and the MSC patch improved the MI cardiac function by providing mechanical support and viable stem cells.
