Extracellular matrix can influence stem cell choices, such as self-renewal,
quiescence, migration, proliferation, phenotype maintenance, differentiation, or
apoptosis. Three aspects of extracellular matrix were extensively studied during
the last decade: physical properties, spatial presentation of adhesive epitopes,
and molecular complexity. Over 15 different parameters have been shown to
influence stem cell choices. Physical aspects include stiffness (or elasticity),
viscoelasticity, pore size, porosity, amplitude and frequency of static and
dynamic deformations applied to the matrix. Spatial aspects include scaffold
dimensionality (2D or 3D) and thickness; cell polarity; area, shape, and
microscale topography of cell adhesion surface; epitope concentration, epitope
clustering characteristics (number of epitopes per cluster, spacing between
epitopes within cluster, spacing between separate clusters, cluster patterns, and
level of disorder in epitope arrangement), and nanotopography. Biochemical
characteristics of natural extracellular matrix molecules regard diversity and
structural complexity of matrix molecules, affinity and specificity of epitope
interaction with cell receptors, role of non-affinity domains, complexity of
supramolecular organization, and co-signaling by growth factors or matrix
epitopes. Synergy between several matrix aspects enables stem cells to retain
their function in vivo and may be a key to generation of long-term, robust, and
effective in vitro stem cell culture systems.
