Abstract
A broad range of technologies have been developed to enable three dimensional (3D) cell culture. Few if any however are adaptable for routine everyday use in a straightforward and cost effective manner. Alvetex(®) is a rigid highly porous polystyrene scaffold designed specifically to enable routine...
