Fibrous-Bed Bioreactor

In fibrous-bed bioreactor, the cells are immobilized on the fibers in the bioreactor.

Following is scanning electron microscope photos of human osteosarcoma cells in an artificial growth medium, a fibrous-bed bioreactor. The cells cling to Dacron fibers. Osteosarcoma is the most common malignant bone tumor. These cells have been genetically-engineered to produce a protein called Del-1.
