<music> cutting edge bio manufacturing aboard the international space station presented by science at nasa most likely you're aware of three d. printing which allows you to design and produce one of a kind pieces uses for a variety of purposes but what if you could use that same technology to manufacture logical materials like new tissue or blood vessels welcome to the world of three d bio manufacturing a cutting edge practice on earth that is being tested aboard the international space station or i._s._s. Dr mike roberts deputy chief scientist at the u._s. National laboratory explains why the space station is critical to bio manufacturing's future. We've been able to grow cells in a lab for well over a century but gravity limits that growth to two dimensions cells can grow <unk> outward but not up and down like they do in the human body also lab cells are often in contact with the glass or plastic that contains them but aboard aboard the space station are experiments will be conducted in microgravity that allows you to build your cell models in three dimensions without being confined to the bottom of a dish or are unable to grow in contact with lots of other cells bio manufacturing imagines the ability to someday grow viable human organ organs composed of specific tissue intersected by blood vessels most organs and thicker tissues in the body have a rich complex network of blood vessels that provide nutrients treatments and remove wastes from the living cells that make up the tissue we currently lack the ability and the tools to engineer these highly branched living networks of vessels inside inside layers of tissues on earth. Another medical advantage to manufacturing biological parts in space is the potential to bypass the body's immune system today organ transplants from donors are prone to rejection because the patient's body perceives the new organ as a foreign object and their immune system tries to attack ticket but with the ability to grow tissue in space a person could conceivably have their own cells used to make their new organ which might avoid the body's rejection.
