Cells Reagents

The collagen sponge for cell culturing is a collagen-based device developed for three-dimensional cell culturing. The collagen porous sponge is prepared from a insoluble type I collagen that is derived from bovine Achilles tendon. Cells can penetrate into the sponge and proliferate three-dimensionally. This technique is very useful for tissue engineering studies.

The 'Honeycomb' collagen sponge has a structure in which uniform pores (250-400 μm) are arranged densely in one direction, into which cells can penetrate and proliferate. This structure facilitates the ready supply of nutrients to the cells inside the sponge, and releases metabolic wastes and biochemical products. Cells can proliferate and fill the lumen to form a uniform cell mass. The 'Honeycomb' collagen sponge is prepared from highly purified bovine dermal type I Atelocollagen and can be degraded by collagenase.
