Estimating the term…
This disclosure provides a three-dimensional (3D) microenvironment presenting defined biochemical and physical cues that regulate cellular behavior and use of the microenvironment. A composition to form the 3D microenvironment is provided by combining one or more natural or synthetic polymeric materials and substrate proteins recombinantly or chemically functionalized with a variety of bioactive peptides such as extracellular matrix-derived or growth factor-derived peptides. The disclosure also provides for devices and methods for screening for optimal combinations of the bioactive motifs in order to create an extracellular microenvironment that can regulate specific cellular behavior such as cell growth, proliferation, migration or differentiation.
An electrospinnable biofunctional composition to engineer 3D extracellular microenvironment comprising two components, an extracellular component and a structural component.
A nanofiber having particles presenting peptide motifs to activate at least one cell surface receptor.
A microenvironment surface presenting at least one ECM-derived peptide motif that regulates cellular behavior.
A process for producing a microenvironment array, the process comprising:
An extracellular microenvironment surface for long-term self-renewal of a pluripotent stem cell, wherein the extracellular microenvironment surface presents signal molecules that support the pluripotent stem cell.
