Abstract
There is provided a matrix and cultivation system for anchorage dependent cells. The matrix is characterized by a substantially increased available effective surface area for cell attachment which is attained by resorting to the use of a fiber network or open-pore foams with suitable pore size. Attachment of the cells can be enhanced by modifying the surface of the substrate. One embodiment comprises a matrix in particle or flake form.
