ABSTRACT:
This invention relates three dimensional porous cell culture matrices or scaffolds which have directional porous structure. More particularly, this invention relates to three dimensional porous cell culture matrices or scaffolds for cell culture which are derived from or contain gums including naturally occurring gums, plant gums, galactomannan gums or derivatives thereof. The invention also relates to methods of making the matrices, articles of manufacture (e.g., cell culture vessels and labware) having such matrices or scaffolds, methods of applying these materials to cell culture surfaces, and methods of using cell culture vessels having these three dimensional porous cell culture matrices or scaffolds.
