Microgravity

Biomedical research offers hope for a variety of medical problems, from diabetes to the replacement of damaged bone and tissues. Bioreactors, which are used to grow cells and tissue cultures, play a major role in such research and production efforts. Anchorage dependent cells on STS-95 will be grown on beads similar to these cells produced during previous investigations. Recombinant proteins may offer the possibility of reducing or eliminating transplant rejections. Research by Synthecon, Inc. using the BioDyn Bioreactor will focus on the preliminary process for growing a proprietary recombinant protein that can decrease rejection of transplanted tissue. The cells producing this protein are anchorage dependent, meaning that they must attach to something to grow. These cells will be cultured in the bioreactor in a medium containing polymer microbeads. Synthecon hopes that the data from this mission will lead to the development of a commercial protein that will aid in prevention of transplant rejection.
