Abstract

The capability of human pluripotent stem cells (hPSCs) to differentiate into a variety of cells in the human body holds great promise for regenerative medicine. Many substrates exist on which hPSCs can be self-renewed, maintained and expanded to further the goal of clinical application of stem cells. In this review, we highlight numerous extracellular matrix proteins, peptide and polymer based substrates, scaffolds and hydrogels that have been pioneered. We discuss their benefits and shortcomings and offer future directions as well as emphasize commercially available synthetic peptides as a type of substrate that can bring the benefits of regenerative medicine to clinical settings.

Keywords: Human pluripotent stem cells, Extracellular matrix protein, Synthetic substrate, Peptide, Polymer, Scaffold, Hydrogel

Core tip: This review article highlights numerous extracellular matrix proteins, peptide and polymer based substrates, scaffolds and hydrogels that have been pioneered for human pluripotent stem cell self-renewal for stem cell-based therapy. The benefits and shortcomings of these substrates as well as future direction that can bring the benefits of regenerative medicine to clinical settings are discussed.
