Abstract: | Many factors contribute to the creation and maintenance of a realistic environment for cell growth in vitro, e.g. the consistency
of the growth medium, the addition of supplements, and the surface on which the cells grow. The nature of the surface on which
cells are cultured plays an important role in their ability to attach, proliferate, migrate and function. Components of the
extracellular matrix (ECM) are often used to coat glass or plastic surfaces to enhance cell attachment in vitro. Fragments
of ECM molecules can be immobilised on surfaces in order to mimic the effects seen by whole molecules. In this study we evaluate
the application of a novel technology for the immobilisation of functional domains of known ECM proteins in a controlled manner
on a surface. By examining the adherence of cultured PC12 cells to alternative growth surfaces, we show that surfaces coated
with motifs from collagen I, collagen IV, fibronectin and laminin can mimic surfaces coated with the corresponding whole molecules.
Furthermore, we show that the adherence of cells can be controlled by modifying the hydropathic properties of the surface
to either enhance or inhibit cell attachment. Collectively, these data demonstrate the application of a new technology to
enable optimisation of cell growth in the tissue culture laboratory. |
