A new injectable tissue engineered scaffold for regenerative medicine

The failure of the application of tissue engineering in clinical trials is questionable. Tissue-engineering scaffolds used in tissue regeneration have micron structures that fail to be analogous to native extracellular matrix (ECM) in terms of both chemical composition and physical structure as a suitable surface structure for cell attachment, proliferation, and differentiation. In this study we designed an artificial ECM in order to mimic the nano-structured topography created by ECM components of native tissue. Selective differentiation of cardiomyocytes cells by self assembly of peptide-amphiphile nanofibers was studied for in vivo cardiac infarction therapy
