Bioinspired Soft Materials to Direct Stem Cell Function and Tissue Regeneration

Highly regulated signals in the stem cell microenvironment, such as growth factor presentation and concentration, matrix stiffness, and ligand adhesion density have been implicated in modulating stem cell proliferation and maturation. Therefore, it is desirable to have independent control over both the biochemical and mechanical cues presented to cells to analyze their relative and combined effects on stem cell function. Accordingly, we have developed synthetic hydrogels and biointerfaces to assess the effects of adhesion ligand presentation and material moduli spanning physiologically relevant ranges (10 to 10,000 Pa) on stem cell function. Employing these soft materials, we have demonstrated that the mechanical and biochemical properties of a stem cell microenvironment can be tuned to regulate the self-renewal and differentiation of different types of stem cells including human embryonic, neural, and mesenchymal stem cells. We have further modified these tunable biomimetic hydrogels with matrix metalloproteinase labile crosslinkers (e.g. MMP-2, 9 &13), to be used as an assistive microenvironment for transplantation of stem cells into diseased or damaged tissue such as the infracted myocardium. These biomimetic hydrogels provide a foundation for systematic development of "pro-survival" microenvironments for cell transplantation and the potential improvement in the long-term results of regenerative therapies. Various examples from our work will be discussed during this presentation.
